EM78P153SNJ 8-bit CMOS мікроконтролер SOP14

Мікроконтролер Маркування: EM78P153SNJ Корпус: SOP-14 8-bit microprocessor with low-power and high-speed CMOS technology Технічні параметри: Operating voltage range: 2.3V~5.5V Available in temperature range: 0°C~70°C Operating frequency range (base on 2 clocks): Crystal mode: DC~20MHz at 5V, DC~8MHz at 3V, DC~4MHz at 2.3V. ERC mode: DC~4MHz at 5V, DC~4MHz at 3V, DC~4MHz at 2.3V. Low power consumption: less then 1.5 mA at 5V/4MHz typical of 15 µA, at 3V/32KHz typical of 1µA, during the sleep mode 1024 × 13 bits on chip ROM Built-in calibrated IRC oscillators (8MHz, 4MHz, 1MHz, 455KHz ) Programmable prescaler of oscillator set-up time One security register to prevent the code in the OTP memory from intruding One configuration register to match the user’s requirements 32× 8 bits on chip registers (SRAM, general purpose register) 2 bi-directional I/O ports 5 level stacks for subroutine nesting 8-bit real time clock/counter (TCC) with selective signal sources and trigger edges, and with overflow interrupt Power down mode (SLEEP mode) Three available interruptions TCC overflow interrupt Input-port status changed interrupt (wake up from the sleep mode) External interrupt Programmable free running watchdog timer 7 programmable pull-high I/O pins 7 programmable open-drain I/O pins 6 programmable pull-down I/O pins Two clocks per instruction cycle The transient point of system frequency between HXT and LXT is around 400KHz.
