FT51A
(Advanced Microcontroller with 8051
Compatible Core)
The FT51A is a multi-featured device that can be ^
targeted at a wide range of functions or ^
applic at ions:

 Industry compatible 8051 core running at a

maximum frequency of 48MHz.
 8 KB of data memory

 16 KB of multi-time programmable (MTP) memory _
 16 KB of shadow memory for fast read access by _
the core.

 USB 2.0 Full Speed hub controller allowing
cascading of multiple FT51A devices

 USB 2.0 Full Speed device controller compatible to
FT12 series

 Supports up to 8 bi-directional endpoints with 2 x
1 KB USB endpoint buffers

 Max packet size is 504 bytes for USB isochronous ^
endpoint and 64 bytes for control / bulk / interrupt _
e nd p o int

 Double buffer scheme for any endpoint, increases
data transfer throughput

 Fully integrated clock generation with no external
crystal required

 Data transfer rates from 300 baud to 3M baud
(RS422, RS485, and RS232) at TTL levels
 PWM Controller
 UART interface support for 7 or 8 data bits, 1 or 2
stop bits and odd / even / mark / space / no parity
 USB Battery Charger Detection allowing optimized
charging profile
