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
applications:
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
endpoint
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
Supports DMA operation
