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
