Product specification
Low voltage 8-bit microcontroller with
6-kbyte embedded RAM
SZF2002
Note
1.
The pin layout has been optimized for easy connection of 256 kbytes Flash ROM (e.g. ATMEL AT29LV010A,
SGS-Thomson M28V201, or AMD Am29F010).

Pulse Width Modulation output.
Reset
. A HIGH level on this pin for at least 12 clock cycles resets the device.
Clock input.
External Access.
When EA is HIGH the CPU executes out of internal program
memory (unless the program counter exceeds 7FFFH). A LOW EA forces the CPU to
execute out of external memory regardless of the value of the Program Counter. This
signal is latched at the falling edge of reset (RST pin). The EA pin has an internal
pull-down. When it is not connected the CPU executes from external memory.
DEBUG enable.
If HIGH, forces standard 80C51 timing signals output at address and
databus. In this mode the databus is multiplexed with the lower 8 bits of the address
bus, and the A0 to A3 lines are used for the RD, WR, ALE and PSEN signals. This
allows a standard 80C51 in-circuit emulator to be connected. For normal operation
connect DEBUG to V
