General Description
The EM77950 from ELAN Electronics is a low-cost and high performance 8-bit CMOS advance RISC architecture microcontroller device.
It has an on-chip 1-Mbps RF driver module/Base Band (BB), Serial Peripheral Interface (SPI), dual Pulse Width Modulation (PWM) with 16-bit resolution, an 8-bit Timer Clock Counter (TCC) and a 16-bit Free Run Timer, multi-channel Analog to Digital Converter (ADC) with 8-bit resolution, Key Wake-up function (KWU), Power-on Reset (POR), Watchdog Timer (WDT), and power saving Sleep Mode.
All these features combine to ensure applications require the least external components, hence, not only reduce system cost, but also have the advantage of low power consumption and enhanced device reliability.
The 52-pin EM77950 is available in a very cost-effective version that provides a single chip solution in designing wireless products.
Features

* Internal Power-on Reset (POR) function
* Code protection function available
* All single cycle (1 clock) instruction except for conditional branches which are two or three cycles.
* Direct, indirect and relative addressing modes
* Low power, high speed CMOS technology
* Power consumption:
- 4 mA @ 3.3V, 6 MHz
- 60 μA @ 3.0V, (RC = 32.768 kHz)
- 1 μA standby current
