Product>>8051 MicroController>>STC8A4K64S2A12 series
 

Features:

  

Core

    Enhanced 8051 Core with single clock per machine cycle (1T)

    Fully compatible instruction set with traditional 8051

    22 interrupt sources and 4 interrupt priority levels

    Online debugging is supported

Operating voltage

    2.0 to 5.5V

    Built-in LDO

Operating temperature

    -40°C~85°C

Flash memory

    Up to 64Kbytes of Flash memory to be used to store user code

    Configurable EEPROM size, 512bytes single page erased, can be repeatedly erased more than 100 thousand times.

    In-System-Programming, ISP in short, can be used to update the application code, no need for programmer.

     Online debugging with single chip is supported, and no emulator is needed. The number of breakpoints is unlimited theoretically.

SRAM

    128 bytes internal direct access RAM

    128 bytes internal indirect access RAM

     4096 bytes internal extended RAM

    RAM expandable externally up to 64 Kbytes

Clock

     Internal 24MHz high precise R/C clock IRC

        Error:±0.3%

        Temperature drift: ±1.0% at the temperature range of -40°C to 85°C and ±0.6% at the temperature range of -20°C to 65°C

     Internal 32KHz low speed IRC with large error

     External 4MHz~33MHz oscillator or external clock

     The three clock source above can be selected freely by used code.

Reset

    Hardware reset

        Power-on reset

        Reset by reset pin with high reset pulse

        Watch dog timer reset

        Low voltage detection reset. 4 low voltage detection levels are provided, 2.2V, 2.4V, V2.7,V3.0

     Software reset

        Writing the reset trigger register using software

Interrupts

     22 interrupt sources: INT0, INT1, INT2, INT3, INT4, timer0, timer1, timer2, timer3, timer4, uart1, uart2, uart3, uart4, ADC, LVD, PCA/CCP, SPI, I2C,
comparator, enhanced PWM, enhanced PWM fault detection

    4 interrupt priority levels

Digital peripherals

    5 16-bit timers: timer0, timer1, timer2, timer3, timer4. Where the mode 3 of timer0 has the Non Maskable Interrupt (NMI in short) function. Mode 0 of

    timer0 and timer1 is 16-bit Auto-reload mode.

     2 high speed UARTs: uart1, uart2, whose baud rate clock source may be fast as FOSC/4

    4 groups of PCA: CCP0, CCP1, CCP2, CCP3, which can be used as capture, high speed output and 6-bits, 7-bits, 8-bits or 10-bits PWM

    8 groups of 15 bit enhanced PWM. Control signal with dead zone can be realized, and external fault detection function is supported.

     SPI: Master mode, slave mode or master/slave automatic switch mode are supported.

     I2C: Master mode or slave mode are supported.

Analog peripherals

     ADC: 16 channels 12 bit ADC

     Comparator

GPIO

     Up to 59 GPIOs: P0.0~P0.7, P1.0~P1.7, P2.0~P2.7, P3.0~P3.7, P4.0~P4.4, P5.0~P5.5, P6.0~P6.7, P7.0~P7.7

     4 modes for all GPIOs: quasi-bidirectional mode, push-pull output mode, open drain mode, high-impedance input mode

Package

     LQFP64, LQFP48, LQFP44
