1 / 113 page  SH79F166A Enhanced 8051 Microcontroller with 10bit ADC 1 V2.2 1. Features 8bits micro-controller with Pipe-line structured 8051 compatible instruction set Flash ROM: 16K Bytes RAM: internal 256 Bytes, external 256 Bytes, LCD RAM 19Bytes EEPROM-like: 1K Bytes Operation Voltage: fOSC = 32.768kHz - 12MHz, VDD = 2V - 5.5V Oscillator (code option) - Crystal oscillator: 32.768kHz - Crystal oscillator: 2MHz - 12MHz - Ceramic oscillator: 2MHz - 12MHz - Internal RC: 12MHz (±2%)/128K 41 CMOS bi-directional I/O pins Built-in pull-up resistor for input pin Four 16-bit timer/counters T2, T3,T4 and T5 One 12-bit PWM Powerful interrupt sources: - Timer2, 3, 4, 5 - INT0, 1, 2, 3 - INT40, INT41, INT42, INT43 - ADC，EUART，SCM - PWM EUART 8channels 10-bits Analog Digital Converter (ADC), with comparator function built-in Buzzer LED driver: - 8 X 8 dots (1/8 duty) - 4 X 8 dots (1/4 duty) LCD driver: - 8 X 19 dots (1/8 duty 1/4 bias) - 4 X 19 dots (1/4 duty 1/3 bias) Low Voltage Reset (LVR) function (enabled by code option) - LVR voltage level 1: 4.3V - LVR voltage level 2: 2.1V CPU Machine cycle: 1 oscillator clock Watch Dog Timer (WDT) Warm-up Timer Support Low power operation modes: - Idle Mode - Power-Down Mode Flash Type Package: QFP44/LQFP44 2. General Description The SH79F166A is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch structure, that helps the SH79F166A can perform more fast operation speed and higher calculation performance, if compare SH79F166A with standard 8051 at same clock speed. The SH79F166A retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and Int0-3.In addition, the SH79F166A provides external 256 bytes RAM, It also contains 16K bytes Flash memory block both for program and data. Also the ADC and PWM timer functions are incorporated in SH79F166A. For high reliability and low cost issues, the SH79F166A builds in Watchdog Timer, Low Voltage Reset function. And SH79F166A also supports two power saving modes to reduce power consumption. |
