CYPRESS INTERNAL USE ONLY Owner : SAYD Cypress Confidential Sales Training 2/21/ FT232R Overview FT232R is a USB to UART interface with Data transfer rates of 3Mbaud at TTL levels Operating supply current in normal node of 15mA Operating supply current in suspend mode of 70µA UART interface support for 7-8 bits and 1-2 stop bits 128 bytes RX buffer and 256 bytes TX buffer Operating voltages from 3.3V to 5.5V Fully integrated 1Kb EEPROM to store device descriptors and CBUS I/O configuration FT232R finds application in USB to UART(RS232,RS422,RS485) converters USB upgradation of legacy peripherals PDA (Personal Digital Assistant) to USB data transfer USB smart card readers FTDI FT232R is one of the most widely used solutions for USB to UART conversion for the last decade FT232R

CYPRESS INTERNAL USE ONLY Owner : SAYD Cypress Confidential Sales Training 2/21/ Challenges Using FTDI FT232R CY7C65213 solves these problems RX buffer of 256 bytes allows for high data transfer rates with minimal data loss Industry’s lowest suspend mode current of 5µA consumes the least power CY7C65213 is a reliable, low power solution for USB to UART converters A USB to DB9 serial converter cable has low suspend current requirements USB to UART converter cables 1. Low FIFO receive (RX) buffer memory leads to unreliable data transfer Transmission rates of a CPU is higher than the receiving rate of the device, hence the device needs RX buffers High transmission rates require RX buffers of high memory size to prevent loss of data FT232R has a low RX buffer size of only 128 bytes 2. High suspend current leads to high power consumption USB to UART cable remains in suspend mode when not transferring data Suspend mode current should be as low as possible to save power FT232R has a high suspend mode current of 70µA
