FT51A Advanced MCU with 8051 Compatible Core IC Datasheet  
Version 1.5  
Document No.: FT_000877  
Clearance No.: FTDI#420  
3.1.2.1  
On-chip Debugger  
The 8051 works with a highperformance “Hardware Assisted Debugger” which manages the  
communication between the core and the software.  
3.1.2.2  
UART / FTDI UART  
There are two UARTs in the system one designed by FTDI and the second incorporatedwithin the 8051  
core. The 8051 UART has a maximum baud rate of up to 60kbps. The FTDI UART gives speeds up to  
3Mbps.  
When the data and control bus are configured in UART mode, the interface implements a standard  
asynchronous serial UART port with full modem control. The UART can support baudrates from 183 baud  
to 3 Mbaud. The maximum UART speed is limited by the CPU clock. The following maximum UART speed  
applies:  
CPU Frequency  
48 MHz  
Maximum UART Speed  
3 Mbaud  
24 MHz  
3 Mbaud  
12 MHz  
1.5 Mbaud  
3.2 Functional Block Descriptions  
The following paragraphs detail each function within the FT51A. Please refer to the block diagram shown  
in Figure 3-1 FT51A Block Diagram.  
3.2.1  
8051 Ports 0 - 3  
The 8051 core has four 8-bit bidirectional ports: P0, P1, P2 and P3. These ports can be fully or partially  
mapped to external pins on the AIO and DIO bus. Firmware can change the pin mapping through IOMUX  
programming. Table 3-1 shows the default pin mapping for all the 4 ports on the LQFP44 and WQFN48  
packages.

3.2.2  
Timers and Watchdog  
Apart from standard 8051 timers the FT51A has four general purpose 16-bit timers A, B, C and D. A 32-  
bit watchdog timer is also provided.
