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.
