Yi Feng Chen Technology 8051 chip cooker

Yi Feng Chen Technology Small appliances IC chip Flash-MCU-SC91F731 1. General Description SC91F731 is a reinforced ultra-fast 1T 8051 Industrial Grade Flash microcontroller instruction set is fully compatible with the traditional 8051 products. SC91F731 within the integrated 8KB Flash ROM (containing 256Byte EEPROM), 256B SRAM, up to 18GP I / O (containing eight high-current LED drive port), 5 external interrupt, two 16-bit timers, 8-channel 10-bit precision ADC, 1 channel 8-bit PWM 2 output to sharing the road, a road 12 Buzzer, 1 serial communication interface (SIF), 1 个 32K Base timer, internal precision 16M / 8M Hz oscillator and other resources. To improve reliability and simplify customer circuit, SC91F731 internal also integrates four selectable voltage LVR, 2.4V ADC reference voltage reference, WDT high reliable power supply circuits. SC91F731 can be widely used in a variety of small household appliances, industrial control and other applications. 2. Main Features Operating voltage: 3.6V ~ 5.5V Operating temperature: -40 to 85 degrees Package: SOP20, DIP20 core: ultra-fast 1T 8051 Memory: 8KB Flash ROM (MOVC ban of 0000 ~ 00FFH address 256B), 256B SRAM System clock: Built-16M / 8M Hz system clock oscillator IC work, you can choose to set the frequency error by the programmer: Crossing (4.5V ~ 5.5V) and (40 degrees, 85 degrees) application environment, not more than ± 2% as an external 32K oscillator IC system clock not only as to the precise timing of the use of Base Timer can wake STOP to cancel this crystal by Code Option, and use as GPIO Low Voltage Reset (LVR): reset voltage has four options; are: 3.5V, 3.7V, 3.9V, 4.1V Default programming for the user to select a value when Flash programmer Code Option: 4-wire serial programming interface interrupt (INT): TIMER0, TIMER1, X32K, PWM, SIF, ADC, INT0 ~ 2,, INT6 ~ 7 of 11 interrupt sources INT0, INT2, INT6 ~ 7 external interrupt 4 interrupt vector entry, only INT1 falling edge interrupt vector as a separate entrance, you can set rising, falling dual edge interrupt interrupt priority can be set two digital peripherals: 18 4 modes can be set strong output GP I / O (containing eight high-current LED driver) 16 the WDT, clock divider ratio 2 standard 80C51 16-bit timers TIMER0 and TIMER1 1 serial communication interface SIF, can be set eight PWM Slave and Master Mode 1 road cycle / adjustable duty cycle can be output to two different time-Pin 1 channel 12 Base Timer accurate analog peripherals Buzzer 1 road from the 32K crystal: 8 channel 10-bit ADC 1) built-in 2.4V reference voltage reference 2) Reference voltage ADC has two options, namely, the internal VDD and 2.4V 3) may ADC conversion complete interrupt set power-saving mode: STOP MODE (also known as POWER DOWN MODE) by INT0 ~ 2, INT6 ~ 7 wake-up timer STOP MODE 32K oscillation generated by an external interrupt wake-STOP MODE 3, 4 pin definitions, application vacuum cleaner, straight hair, electric car meter, LED control, HID, charger, foot, touch button, various small appliances, pricing scale, soybean milk, hood, disinfecting cabinet, pressure cookers, rice cookers, heaters, mobile air conditioning, instrumentation, industrial, microwave, tasteless fan Shenzhen Yi Feng Chen Technology Co., Ltd. offers a variety of small appliances chip, Flash-MCU, also provides 6-axis air mouse program, 9-axis air mouse program, 6-axis IR learning programs air rats, with somatosensory air mouse program, with Bluetooth air mouse program.
