General Description
The ZEN8105 is a fast 8051 compatible micro-controller with a redesigned CPU of no wasted clock and memory cycles.
Typically, it will be faster than and exhibit better performance than the traditional 8051 at the same oscillator frequency.
The ZEN8105 retains most features of the standard 8051. These features include internal 256 bytes RAM and two 16-bit
timer/counters. In addition, the ZEN8105 provides external 512 bytes RAM and another 16-bit timer/counter compatible with
8052. It contains a 16K Bytes Flash memory block for program and data.
Some standard serial communication modes such as EUART and SPI are supported in ZEN8105. Also the ADC together
with built-in digital compare function and PWM timers are incorporated in ZEN8105.
It also provides the following standard features: on-chip watchdog timer, low voltage reset function. It provides two power saving
modes to reduce the power consumption.
