8XC152JA is an 8-bit microcontroller produced by Intel Corporation. This microcontroller is based on the MCS-51 CPU and has a multi-protocol serial communication interface, full duplex/half duplex communication mode, MCS-51 compatible UART, 64KB program memory addressing, 64KB data memory addressing, 256 bytes on-chip RAM, dual on-chip DMA channels, 11 interrupt sources and other features.
The 8XC152 series is a highly integrated 8‑bit microcontroller designed for cost‑sensitive, high‑speed serial communications. It supports multiple serial protocols, dual on‑chip DMA channels, and offers up to 64 KB of program and data memory addressing. The device includes five or seven I/O ports, two general‑purpose timers/counters, and eleven interrupt sources.
The datasheet details pin functions for each port, oscillator options (on‑chip and external), absolute maximum ratings, DC electrical characteristics, and power‑saving modes such as Idle and Power‑Down. Design notes address race conditions, interrupt priorities, and revision differences.
