FT51A
(Advanced Microcontroller with 8051
Compatible Core)
Supports DMA operation
The FT51A is a multi-featured device that can be
targeted at a wide range of functions or
I2C Master & Slave functionality
applications:
SPI Master & Slave functionality
Industry compatible 8051 core running at a
maximum frequency of 48MHz.
245 FIFO module provides a simple FIFO interface
to transmit and receive data
8 KB of data memory
Timer and Watchdog
16 KB of multi-time programmable (MTP) memory
Up to 16 dedicated digital IO pins
Up to 16 multiplexed analogue / digital IO pins
Support ADC function on analogue IO pins
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
IO Mux control for maximum flexibility in pin
selection
USB 2.0 Full Speed device controller compatible to
FT12 series
Configurable IO pin output drive strength; 4 mA
(min) and 16 mA (max)
Supports up to 8 bi-directional endpoints with 2 x
1 KB USB endpoint buffers
+5V Single Supply Operation
Internal 3.3V/1.8V voltage regulators
Integrated power-on-reset circuit
Max packet size is 504 bytes for USB isochronous
endpoint and64 bytes for control / bulk / interrupt
endpoint
Low operating and suspend current; 20 mA
(active) and 150 uA (suspend)
Double buffer scheme for any endpoint, increases
data transfer throughput
