HS23P2022 is MCU with low power consumption, high speed, high noise tolerance and EPROM/ROM based on 8-bit CMOS.RISC has a total of 42 instructions, except that the branch instructions are two-cycle instructions, and the rest are single-cycle instructions. This easy-to-use, easy-to-remember instructions greatly reduce the development time. HS23P2022 includes power-on Reset POR, Brown-out Reset BOR, power-up Reset Timer PWRT, oscillator Start up Timer OST, Watchdog Timer, EPROM/ROM, SRAM, 3-state I/O port (can be set to pull-up/pull-down, open drain), Power-saving sleep mode, 8-bit timer/counter with 8-bit preset,independent interrupt, sleep wake-up mode and reliable code protection, there are two oscillating sources available for user configuration, including a power-saving oscillating source and a low-power oscillator. HS23P2022 can access 2K×13 program storage space, it can directly or indirectly access registers and data storage area, all special function registers distributed in the data storage area contain specific program Pointers..
