1. GENERAL DESCRIPTION
The W79E8213 series are an 8-bit 4T-8051 microcontroller which has Flash EPROM which is
programmable by ICP (In Circuit Program) or by hardware writer. The instruction set of the W79E8213
series are fully compatible with the standard 8052. The W79E8213 series contain a 4Kbytes of main
Flash EPROM; a 128bytes of RAM; two 16-bit timer/counters; 4-channel 10-bit PWM; 3 edge detector
inputs; 8-channel multiplexed 10-bit A/D convert. The W79E8213 series supports 128 bytes NVM Data
Flash EPROM. These peripherals are supported by 10 sources four-level interrupt capability. To
facilitate programming and verification, the Flash EPROM inside the W79E8213 series allow the
program memory to be programmed and read electronically. Once the code is confirmed, the user can
protect the code for security.

CRYSTAL2: This is the crystal
oscillator output. It is the
inversion of XTAL1. Also a
I/O configurable i/o pin.
When operating as I/O, it
supports 4 output modes and
TTL/Schmitt trigger.
CRYSTAL1: This is the crystal
oscillator input. This pin may be
driven by an external clock or
I/O configurable I/O pin.
When operating as I/O, it
supports 4 output modes and
TTL/Schmitt trigger.
* TYPE: P: power, I: input, O: output, I/O: bi-directional, H: pull-high, L: pull-low, D: open-drain.
Table 5-1: Pin Description
Note:
On power-on-reset, all port pins will be tri-stated.
After power-on-reset, all port pins state will follow CONFIG0.PRHI bit definition.
