Product details
Overview
S9S12DT12F1MPVE from NXP (formerly Freescale) is a 16-bit HCS12 microcontroller with 128 KB Flash, 8 KB RAM, and integrated CAN 2.0B controller, designed for automotive body control and industrial embedded applications requiring real-time I/O management, deterministic timing, and robust communication. It operates at up to 25 MHz bus frequency, supports 5V tolerant I/O, and includes dual ATD converters (10-bit, 16-channel), 8-channel PWM, and enhanced capture timer.
For engineers reviewing the S9S12DT12F1MPVE datasheet, S9S12DT12F1MPVE pinout, S9S12DT12F1MPVE application, or S9S12DT12F1MPVE equivalent, key selection criteria include CAN interface support, Flash memory size, 5V I/O compatibility, on-chip voltage regulator operation, and background debug capability via BKGD pin.
Technical Context
The S9S12DT12F1MPVE implements the HCS12 CPU12 core with 16-bit data path and 24-bit address space, executing instructions in single-cycle or multi-cycle modes depending on addressing mode. Its CRG block integrates PLL with programmable multiplication factor (K = 1–64) and selectable oscillator source (crystal, ceramic resonator, or external clock).
Memory subsystem includes 128 KB on-chip Flash organized in 1 KB sectors with row programming, 8 KB RAM, and 1 KB EEPROM with 100K write cycles. Peripheral integration features two independent MSCAN modules, dual 10-bit ATD converters with simultaneous sampling, and 8-channel 8-bit PWM with center-aligned and edge-aligned modes.

Pinout & Package
Package: 112-pin LQFP (16 × 16 mm, 0.4 mm pitch, case 987), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Active-low reset input | Asynchronous hardware reset with internal pull-up; initiates full register initialization and Flash security lock release |
| BKGD / TAGHI / MODC | Background debug pin | Single-wire BDM interface for non-intrusive debugging, flash programming, and real-time register inspection |
| PJ7 / TXCAN0 | CAN0 transmit output | CMOS-level CAN high-speed differential transmitter output, requires external transceiver (e.g., MC33883) |

Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum bus frequency supported by the S9S12DT12F1MPVE?
The S9S12DT12F1MPVE supports a maximum bus frequency of 25 MHz, achieved via its on-chip PLL with programmable multiplication factor (K = 1–64) and external crystal or oscillator input. This frequency is maintained across the full –40°C to +125°C operating range and is validated in the device's electrical characteristics table under "Bus Clock Frequency".
Does the S9S12DT12F1MPVE include an integrated voltage regulator?
Yes, the S9S12DT12F1MPVE includes an integrated 5V-to-2.5V voltage regulator controlled by the VREGEN pin. When VREGEN is asserted high, the regulator supplies VDDR (core logic voltage); this eliminates the need for an external 2.5 V LDO in single-rail 5 V designs, reducing BOM count and PCB area.
How many CAN controllers are integrated into the S9S12DT12F1MPVE?
The S9S12DT12F1MPVE integrates two independent MSCAN 2.0B-compliant controllers (CAN0 and CAN1), each supporting up to 1 Mbit/s baud rate, 16-message mailboxes, and automatic retransmission. Pins PJ7/PJ6 and PM5/PM4 are assigned to CAN0 and CAN1 respectively, with dedicated TX/RX functions.
What is the Flash memory endurance specification for the S9S12DT12F1MPVE?
The S9S12DT12F1MPVE specifies 100,000 program/erase cycles for its 128 KB on-chip Flash memory, with guaranteed 10-year data retention at +85°C. These values are confirmed in the "NVM Reliability Characteristics" section of the official device user guide and apply to standard row-programming operations.
Is the S9S12DT12F1MPVE pin-compatible with other HCS12 derivatives like the MC9S12DJ64?
No, the S9S12DT12F1MPVE is not pin-compatible with the MC9S12DJ64. While both belong to the HCS12 family and share architectural similarities, the S9S12DT12F1MPVE uses a 112-pin LQFP package with distinct pin assignments-including dual CAN, expanded PWM, and VREGEN-whereas the MC9S12DJ64 is offered in 80-pin QFP and 112-pin LQFP variants with different peripheral mappings and no integrated regulator.
