EM77F900数据手册Elan中文资料规格书

描述 Description

The EM77F900 from ELAN Technology is a low-cost and high performance 8-bit CMOS advance RISC architecture microcontroller device. It has an on-chip 1-Mbps RF driver Baseband (BB), Universal Serial Bus Hub (USB Hub), 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 10-bit resolution, Key Wake-up function (KWU), Power-on Reset (POR), Watchdog Timer (WDT), security Protection Bit, 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 100-pin EM77F900 is available in a very cost-effective flash version. It is also suitable and flexible for any quantities of volume production
