Preliminary Enhanced 8051 Microcontroller with 10-bit ADC Features 8051 patible Pipe-lined instruction based on the single-chip 8-bit micro-controller Flash ROM: 8K Bytes RAM: internal 256 Bytes Operation voltage: f OSC=400k - 12MHz, VDD=4.0V - 5.5V Oscillator (Code option): Ceramic resonator: 400k - 12MHz Internal RC oscillator: 12MHz 25 CMOS general purpose I/O ports 4 open-drain type I/O available Built-in pull-high resistor for I/O Three 16-bit timer / counters: T0, T1 & T2 One 12-bit PWM Timer Two 8-bit PWM Timers Powerful interrupt sources: Timer0, Timer1, Timer2 External interrupt 0~1 External interrupt 4: 6 inputs ADC, EUART, SPI, PWM Enhanced UART SPI interface (Master/Slave Mode) 10-bit 8 channel Analog Digital Converter (ADC) with built-in pare function Buzzer driver Built-in low voltage reset function (enabled by code option) LVR voltage level: 3.1V CPU Machine cycle: 1 oscillator clock Built-in Watch Dog Timer (WDT) Warm-up timer for power-on reset Support Low power operation modes: IDLE Mode Power-Down Mode Flash type Package: 28-pin plastic SOP/Skinny DIP Package General Description The SH79F081 is a fast 8051 patible micro-controller with a redesigned CPU of no wasted clock and memory cycles. Typically, it will be faster than and exhibit better performance than the traditional 8051 at the same oscillator frequency. The SH79F081 retains most Features of the standard 8051. These Features include internal 256 bytes RAM and two 16-bit timer/counters. In addition, the SH79F081 provides another 16-bit timer/counter patible with 8052. It contains a 8K Bytes Flash memory block for program and data. Some standard serial munication modes such as EUART and SPI are supported in SH79F081. Also the ADC together with built-in digital pare function and PWM timers are incorporated in SH79F081. It also provides the following standard Features : on-chip watchdog timer, low voltage reset function. It provides two power saving modes to...
