Introduction
This manual describes how to set up Zilog’s Z51F3221 Development Kit (Zilog part num-
ber Z51F3221000ZCOG) and use it to evaluate your Z8051-based designs and applica-
tions.
The Kit features a development board consisting of five LEDs, five pushbuttons, a buzzer,
eight 14-segment LCD digits, port pin headers and a UART-to-USB port. The Board fea-
tures the Z51F3221 MCU in a 80-pin LQFP package, plus a DBG connector to connect
the Board to a host development PC using the Z8051 USB On-Chip Debugger (OCD)
cable. For more details about the Z51F3221 MCU, please refer to the Z51F3221 Product
Specification (PS0300).
