S9S12VR32F0VLC is an NXP Freescale 16‑bit microcontroller in the S9S12VR32F0 family. It uses the HCS12V/HC12‑class 16‑bit CPU core and combines on‑chip flash and RAM with a rich peripheral set.
Key points
- Core: 16-bit HCS12V‑class CPU with Harvard architecture features.
- Memory: on‑chip Flash and RAM (exact sizes vary by device variant).
- Peripherals: timers, PWM, ADCs, comparators, multiple serial interfaces (SCI/SPI/I2C), watchdog; DMA on some variants.
- Variant/suffix: VLC denotes a specific device/packaging/grade variant; consult the datasheet for exact memory, pin count, and package details.
- Applications: automotive and industrial control, motor drives, sensing/embedded control requiring real‑time performance with modest power.
- Getting started: obtain the official datasheet/user guide, use the Freescale/NXP CodeWarrior (legacy S12 tools) or equivalent S12 development toolchain, and program via the on‑chip flash with a debug interface.
For precise specs, refer to the device datasheet.
