Product details
Overview
S9S12D64F0VFUE from NXP (formerly Freescale) is a 16-bit HCS12 microcontroller with 64 KB on-chip Flash, 4 KB RAM, and integrated CAN 2.0B controller. It operates at up to 25 MHz bus frequency, supports 5V I/O tolerance, and features dual 10-bit ATD converters (ATD0/ATD1), 8-channel PWM, and background debug interface (BDM). It is used in automotive body control modules requiring deterministic real-time response and CAN network integration.
For engineers reviewing the S9S12D64F0VFUE datasheet, S9S12D64F0VFUE pinout, S9S12D64F0VFUE application, or S9S12D64F0VFUE equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts for automotive embedded control design.
Technical Context
The S9S12D64F0VFUE implements the HCS12 CPU12 core with 16-bit data path, 24-bit address space, and instruction set backward-compatible with HC12. Its CRG block supports multiple clock sources including external crystal (1–8 MHz), ceramic resonator, or external clock input, with PLL multiplication enabling stable 25 MHz bus operation.
It integrates MSCAN for ISO 11898-compliant CAN communication, two independent 10-bit ATD converters with 16-channel analog multiplexing, and an enhanced capture timer (ECT) with four pulse accumulators and eight input capture/output compare channels - all operating under single-cycle interrupt latency and configurable priority levels.
