Product details
Overview
MC9S12XEP768MAG from NXP Semiconductors (formerly Freescale) is a 16-bit automotive microcontroller featuring the CPU12X core, 768 KB Flash, 48 KB RAM, and Memory Protection Unit (MPU) with ECC for fault-tolerant operation. It integrates five MSCAN modules, dual ATD converters (8/10/12-bit), XGATE co-processor running at 100 MHz, and supports -40°C to 125°C ambient operation - deployed in body control modules requiring real-time CAN/LIN gateway functionality.
For engineers reviewing the MC9S12XEP768MAG datasheet, MC9S12XEP768MAG pinout, MC9S12XEP768MAG application, or MC9S12XEP768MAG equivalent, key selection criteria include MPU-enabled system integrity, full CAN performance via XGATE offload, non-multiplexed external bus support (in 208-pin MAPBGA), 50 MHz CPU bus frequency, and automotive-grade temperature range compliance.
Technical Context
The MC9S12XEP768MAG implements a dual-core architecture: the 16-bit CPU12X executes main application code at up to 50 MHz bus speed, while the programmable XGATE RISC co-processor handles time-critical I/O tasks-including full CAN mailbox management and LIN protocol framing-at 100 MHz, eliminating CPU intervention and wait states. Both cores share unified memory space with ECC-protected Flash and MPU-enforced memory region isolation.
Its system integrity features include hardware-based Memory Protection Unit (8 configurable regions, 8-byte granularity), single-bit error correction/double-bit detection on Flash and D-Flash, supervisor/user mode execution control, and configurable windowed COP watchdog. The CRG includes a frequency-modulated PLL (IPLL) for EMC reduction and fast wake-up from STOP mode using internal oscillator.
