◆ GENERAL DESCRIPTION
      The KXD8P53 device is a high performance, low-cost, high noise immunity, OTP-based 8-bit CMOS technology microcontroller. Its operation kernel is implemented with RISC architecture with only 42 instructions.All instructions are single cycle except for program branches, which wi l l take two cycles. The easy- to- use instruction set makes development easy.
      The KXD8P53 product is equipped with Power-on Reset (POR),Power-on Reset Timer (PORT), Brown-out Reset (BOR), Watchdog Timer, OTP, SRAM, tri-state I/O port, I/O pull-high/ pull-low/ open-drain control, Power saving SLEEP mode, real time programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for OTP products. With the 1K×13 OTP-ROM feature the KXD8P53 provides a convenient way of developing and verifying.
