HS23P1820 is 8-bit MCU manufactured by low-power and high-speed CMOS process. It has built-in 1k*14 bit ROM and 64Byte SRAM, including three 12 bit PWM and configurable port comparator module.

¡ô 42 RISC instructions, except that the jump instruction is two cycles, all instructions are single cycle

¡ô 14-bit wide instruction, 8-bit wide data path, 5-level deep hardware stack

¡ô Support GOTO instruction full ROM jump, support full ROM subroutine call

¡ô 1K¡Á14 program memory

¡ô 64 x 8 bit universal register

¡ô Direct and indirect addressing

¡ô 8 bit real-time clock with 1 programmable predivider (TC0)

¡ô 12 bit real-time clock with 1 programmable predivider (TP0)

¡ô Configurable port comparator resources

¡ô Internal power reset circuit (POR), built-in undervoltage reset (BOR)

¡ô Power-on reset timer (PWRT) and oscillator start timer (OST)

¡ô Watchdog timer(WDT) with high reliability of internal crystal, enabled or disabled by software

¡ô one group of I/O ports can be configured with pull-up, pull-down, and leak-open states

¡ô 4 working modes can be switched at will: normal mode, low speed mode, sleep mode and green mode

¡ô Wake up sleep: INT/INT1 pin interrupt, IOB input state change, TC0 overflow wake up, COMP wake up

¡ô Wake up green: INT/INT1 pin interrupt, IOB input state change, TC0, TP0 overflow wake up, COMP wake up Energy-saving sleep mode, programmable code protection

¡ô Optional oscillator options: internal high speed oscillator, internal low speed oscillator, external low speed crystal oscillator

¡ô 6 kinds of interrupts available: TC0 overflow interrupt, IOB port change interrupt, INT/INT1 interrupt, TP0 overflow interrupt, interrupts for comp comparisons

¡ô Wide operating voltage range: 2.2V to 5.5V
