7 MAX II: The Lowest-Cost CPLD Ever
New Logic Architecture 1/2 the Cost 1/10 the Power Consumption 2X the Performance 4X the Density Non-Volatile, Instant-On Supports 3.3-, 2.5- & 1.8-V Supply Voltages The four key benefits are compared to MAX: ½ cost; 1/10 power; 2X performance; 4X density. Non-volatility, instant-on, single-chip are “must have” characteristics of a CPLD. Flexible supply voltage details – 3.3V & 2.5V are a single ordering code; 1.8V is a separate ordering code (separate mask set). 1.8V option will be same price, same performance, with lower power. Breakthrough Technology to Expand the Market

8 Flexible Supply Voltage
On-Chip Voltage Regulator Accepts 3.3-, 2.5- & 1.8-V Supply Inputs Internally Converted to 1.8-V Core Voltage 2.5 V 3.3 V 1.8 V Two sets of ordering codes, e.g. EPM1270 (2.5V/3.3V) and EPM1270G (1.8V). Performance and price are the same. Power is much lower in the 1.8V version (2mA standby vs. 12mA standby) because it bypasses the regulator. 3.3/2.5V version will be available first. 1.8V version will follow at a later time. Did not make 1 single device with all 3 Vcc options because we wanted to have a low power device (1.8V). This bypasses the voltage regulator so it doesn’t draw the current associated with that regulator. Convenience of 3.3 V with the Power & Performance of 1.8 V

9 MAX II Device Family Device Logic Elements (LEs) Typical Macro-cells
User I/O Pins Speed Grades Fastest tpd1 (ns) User Flash Memory (bits) EPM240 240 192 80 3, 4, 5 4.7 8,192 EPM570 570 440 160 5.5 EPM1270 1,270 980 212 6.3 EPM2210 2,210 1,700 272 7.1 Densities lower than 128 MCs addressed with current MAX device families. They still meet the fitting, performance and I/O requirements of current designs. Typical macrocells are shown to give an approximate density for designers who are accustomed to thinking in macrocells. These are not absolute conversions, but are based on a 1.3 logic element to 1 macrocell ratio, based on a suite of benchmark designs. The speed grades are FPGA-like and do NOT represent absolute tpd. -3 is the fastest, -4 is medium and -5 is slowest. Each density has a different spec for each speed grade.

10 MAX II Packaging & User I/O Pins
Device 100-Pin TQFP1 0.5-mm Pitch 16 x 16 mm 144-Pin TQFP 0.5-mm Pitch 22 x 22 mm 256-Pin FBGA2 1.0-mm Pitch 17 x 17 mm 324-Pin FBGA 1.0-mm Pitch 19 x 19 mm EPM240 80 EPM570 76 116 160 EPM1270 212 EPM2210 204 272 MAX II is offered in four low-cost packages. These are NOT pin-compatible with MAX CPLDs. Each package was optimized for one specific density to have the max number of I/Os for that package. The EPM570 in the F256 was not the density optimized for that package, which is why it only has 160 I/O. As you increase in density in the same package, you lose I/O to extra GND and VCC pins. The exception is the EPM1270 in the T144 package, which has enough GND and VCC pins, so it doesn’t “lose” any from the EPM570 in the same package. Denotes Vertical Migration Notes: 1. TQFP: thin quad flat pack 2. FineLine BGA® package (1.0-mm pitch)

12 MAX II Architecture Logic Elements (LEs) Staggered I/O Pads
The MAX II floorplan consists of a staggered ring of I/O, which are optimized for small size & pad pitch. This “donut” ring of I/Os defines the actual die size. Inside the I/O ring, we used SRAM-based, logic elements (4-input LUT plus register) to achieve the highest logic efficiency at the lowest price points. The configuration flash memory block and user flash memory block are the non-volatile part of the device. The configuration flash memory loads the design into the SRAM core upon power up, and the user flash memory (8Kb) can be used to store user data. The user does not have access to the config flash memory block. The config flash memory block size ranges from Kb, depending on device density. This depiction is a marketing diagram – the actual floorplan shape is shown in the datasheet & in the software. Configuration Flash Memory JTAG & Control Circuitry User Flash Memory

Every device has the same number of user flash memory bits, 8192. Current program/erase spec is for 100 cycles. Serial EEPROM manufactures – ST, Philips, Atmel, Dallas-Maxim usually have different interfaces like SPI, I2C, serial or parallel Manufacturing Data – Date, serial number, test information, firmware, board ID System Parameters – interrupt address map, IP or port address, Laser or Motor bias current, analogue offsets User Parameters – radio channel or telephone number presets User Flash Memory Block

16 What is Nios II? Altera’s Second Generation Soft-Core 32 Bit RISC Microprocessor Developed Internally By Altera Harvard Architecture Royalty-Free - Nios II Plus All Peripherals Written In HDL - Can Be Targeted For All Altera FPGAs - Synthesis Using Quartus II Integrated Synthesis Avalon Switch Fabric UART GPIO Timer SPI SDRAM Controller On-Chip ROM RAM Nios II CPU Debug Cache FPGA Nios II is a soft-core 32 bit RISC microprocessor that has been developed internally by Altera. It’s based on a Harvard architecture with a 32-bit instruction and data path, separate instruction and data cache, and 32 general purpose registers, and three formats of triadic instructions. It’s closely related to the public domain Stanford MIPS. It’s similar to Nios but is higher performance, has an improved software development flow using the new Nios II IDE (which will be discussed as the presentation rolls along), and it now comes in three “flavors” which I will also discuss shortly. So what does it mean to say “soft-core” processor? It means that the processor, itself, if synthesized out of the logic elements of the particular device architecture that you are programming your part into. In other words, the up is buried in the FPGA. This differs significantly from the common notion of what embedded processors are (ie. off the shelf discrete up’s that you can purchase and implement on a board), and it also differs significantly from a custom ASSP-type hard-core processor which is really a dedicated region of silicon where a processor core gets pre-fabricated into the FPGA. That region of the FPGA will always have the same function on your chip (ie. to be a microprocessor). The soft-core processor is constructed from general purpose gates, routing resources, etc. and offers tremendous flexibility advantages over the more conventional microprocessors, and we’ll get into why this is so as we move along. NB Configurable Soft-Core Processor World’s most versatile processor

20 Licensing Nios II Delivered As Encrypted Megacore
Licensed Via Feature Line In Existing Quartus II License File Consistent With General Altera Megacore Delivery Mechanism Enables Detection Of Nios II In Customer Designs (Talkback) No Nios II Feature Line (OpenCore Plus Mode) System Runs If Tethered To Host PC System Times Out If Disconnected from PC After ~ 1 hr Nios II Feature Line (Active Subscriber) Subscription and New Dev Kit Customers Obtain Licenses From Nios II CPU RTL Remains Encrypted Nios II Source License Available Upon Request On Case-By-Case Basis Included With Purchase Of Nios II ASIC License Nios II ships as an encrypted megacore, just like all other megacore IP from Altera. There are three ways to use Nios II depending on the license: 1. No Nios II License File Feature Line . Nios II will generate FPGA configuration files that operate in OpenCore Plus mode. In other words, as long as the customer.s board is tethered to the host PC (Quartus II), the Nios II system will run. After they disconnect from the host PC (~ 1 hour), the design will timeout and stop running. OpenCore Plus lets customers design, simulate and run Nios II based designs without having to purchase a development kit. 2. Nios II License File Feature Line (Active Subscriber) . Customers who purchase a Nios II development kit, or who receive a Nios II upgrade (i.e. all active Nios subscribers as of May, 2004), must request a Nios II license from the Altera web site which will add a FlexLM feature line to their Altera license file which will enable them to generation configuration files that have no time limit. The RTL generated for the Nios II CPU core is encrypted. Nios II Source License . Customers who purchase a Nios II ASIC license will get an additional feature line to enable plain text RTL generation of the Nios II processor core. If you have a customer who absolutely insists on getting full source code, it can be made available on a case-by-case basis. -- Note: Nios II IDE does not require a license. Thus, you do not require a license to develop code for use with Nios II. Also, you can sort out a license server arrangement for Quartus II and Nios II.
