Description

STC12C5A60S2 is a single-chip microcontroller based on a high performance 1T architecture 80C51 CPU, which is produced by STC MCU Limited. With the enhanced kernel, STC12C5A60S2 executes instructions in 1~6 clock cycles (about 6~7 times the rate of a standard 8051 device), and has a fully compatible instruction set with industrial-standard 80C51 series microcontroller. In-System-Programming (ISP) and In-Application- Programming (IAP) support the users to upgrade the program and data in system. ISP allows the user to download new code without removing the microcontroller from the actual end product; IAP means that the device can write non-valatile data in Flash memory while the application program is running.The STC12C5A60S2 retains all fea- tures of the standard 80C51. In addition, the STC12C5A60S2 has two extra I/O ports (P4 and P5), a 10-sources, 4-priority-level interrupt structure, 10-bit ADC, two UARTs, on-chip crystal oscillator, a 2-CHANNEL PCA and PWM, SPI, a one-time enabled Watchdog Timer. STC12C5A60S2 Features • Enhanced 80C51 Central Processing Unit, 1T per machine cycle, faster 6~7 times than the rate of a standard 8051.• Operating voltage range:5.5v~3.5v or 2.2v ~3.6V(STC12C5A60S2)• Operating Frequency range:0 -35MHz, is equivalent to standard 8051:0~420MHz• On-chip 8/16/20/32/40/48/52/56/60/62K FLASH program memory with flexible ISP/IAP capability• On-chip 1280 byte RAM:256byte scratch-pad RAM and 1024 bytes of auxiliary RAM• Be capable of addressing up to 64K byte of external RAM• Dual Data Pointer(DPTR) to speed up data movement• Code protection for flash memory access• Excellent noise immunity, very low power consumption• four 16-bit timer/counter, be compatible with Timer0/Timer1 of standard 8051,2-channel PCA can be available as two timers• 10 vector-address, 4 level priority interrupt capability• One enhanced UART with hardware address-recognition and frame-error detection function• Secondary UATR with self baud-rate generator• One 15 bits Watch-Dog-Timer with 8-bit pre-scaler (one-time-enabled)• SPI Master/Slave communication interface• Two channel Programmable Counter Array (PCA)• 10-bit ,8-channel Analog-to-Digital Converter (ADC)• Simple internal RC oscillator and external crystal clock• Power control: idle mode (all interrupt can wake up IDLE mode), power-down mode (external interrupt can wake up Power-Down mode ) and slow down mode• Power down mode can be woken-up by PCA_pin ,RXD_pin, T0/T1 pin and external interrupts (INT0,INT1)• 44/40/36 programmable I/O ports are available• Programmable clock output Function T0 output the clock on P3.4, T1 output the clock on P3.5, BRT output the clock on P1.0• External low-voltage detector function (P4.6, the EA pin at the pin location of standard 8051)• Five package type: LQFP-44,LQFP-48,PDIP-40,PLCC-44,QFN-40
