Detailed Description

FT51A is a MCU series which includes the following features:USB client and USB hub interfaces, 8051 core, 8-bit ADC, UART, SPI, I²C, 245FIFO and PWM.

The UMFT51AA is a module which is designed to plug into a standard 0.6” wide 40 pin DIP socket.

The UMFT51AA is built with a FT51AQ; many of the features of the FT51AQ can be utilized with this module.

FT51A Features:

• 8051-compatible core running at a maximum frequency of 48 MHz
• 8051 peripheral set
• 16 kB program/shadow memory
• True Zero Wait States operation up to 48 MHz
• FT12 series compatible USB2.0 Full-Speed/Low-Speed peripheral controller with Battery Charger Detection (BCD)
• USB downstream port
• Enhanced UART with transfer rates from 300 baud to 3M Baud
• Integrated hardware debugger
• PWM Controller
• I²C master/slave controller
• SPI master/slave controller
• 4 extra timers plus watchdog function
• Integrated clock generation, no external crystal required.
• 16 Analog IO Cells for ADC functions
• Up to 16 Digial IO
• USB DFU Bootloader
• Integrated power-on-reset circuit
• +5 V single supply operation
• Internal 3.3 V/1.8 V LDO regulators
• Low operating and suspend current 20 mA (active) and 150 uA (suspend)

In addition to the features of the FT51A, the UMFT51AA has the following features:

• PCB assembly module is designed to fit a standard 15.24 mm (0.6”) wide 40 pin DIP socket. Pins are on a 2.54mm (0.1”) pitch.This module is a drop in replacement for an 8051 microcontroller.
• An on board USB type A socket and plug allow modules to be connected to a PC via a standard A extension cable or directly. This module is also capable of cascading several modules by utilizing the USB hub feature.
• Debugger interface header used for debugging and programming the FT51AQ. Designed for operation with the FTPD-1 programmer/debugger module.
• Onboard jumper for configuring the FT51AA to be in selfpowered or USB powered modes.
