1 / 86 page  SH79F084B Enhanced 8051 Microcontroller with 10bit ADC 1 V2.1 1. Features 8bits micro-controller with Pipe-line structured 8051 compatible instruction set Flash ROM: 8K Bytes RAM: internal 256 Bytes, external 256 Bytes EEPROM-like: 512 Bytes Operation Voltage: fOSC = 30kHz - 16.6MHz, VDD = 2.8V - 5.5V Oscillator (code option) - Crystal oscillator: 32.768kHz - Crystal oscillator: 4MHz - 16.6MHz - Ceramic oscillator: 2MHz -16.6MHz - Internal RC: 16.6MHz (±2%) - External clock: 30kHz - 16.6MHz 14 CMOS bi-directional I/O pins 5 high current drive ports Three 16-bit timer/counters T0, T1and T2 Powerful interrupt sources: - Timer0, 1, 2 - INT0, 1, 2 - ADC, EUART, SCM, PWM, LPD One 8-bit PWM EUART Low voltage detect (LPD) 6 channels 10-bits Analog Digital Converter (ADC), with comparator function built-in Low Voltage Reset (LVR) function (enabled by code option) - LVR voltage level 1: 4.1V - LVR voltage level 2: 3.7V - LVR voltage level 3: 2.8V CPU Machine cycle: 1 oscillator clock Watch Dog Timer (WDT) Warm-up Timer System Clock Monitor (SCM) Support Low power operation modes - Idle Mode - Power-Down Mode Low power consumption Flash Type Package: SOP 16Pin 2. General Description The SH79F084B is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch structure, that helps the SH79F084B can perform more fast operation speed and higher calculation performance, if compare SH79F084B with standard 8051 at same clock speed. The SH79F084B retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and INT0-2.In addition, the SH79F084B provides external 256 bytes RAM, It also contains 8K bytes Flash memory block both for program and data. Also the ADC and PWM timer functions are incorporated in SH79F084B. For high reliability and low cost issues, the SH79F084B builds in Watchdog Timer, Low Voltage Reset function. And SH79F084B also supports two power saving modes to reduce power consumption. |
