Product details
Overview
S912ZVHY64F1VLQ from NXP is a 16-bit S12Z MagniV mixed-signal microcontroller operating at 32 MHz bus frequency, integrating automotive voltage regulation (5–18 V), dual CAN/LIN physical layers, 4-channel stepper motor control with stall detection, and a 4×40-segment LCD controller - deployed in automotive instrument clusters requiring real-time gauge actuation and fault-resilient display.
For engineers reviewing the S912ZVHY64F1VLQ datasheet, S912ZVHY64F1VLQ pinout, S912ZVHY64F1VLQ application, or S912ZVHY64F1VLQ equivalent, key selection criteria include its integrated CAN PHY + LIN PHY, 64 KB flash with ECC, 4 KB EEPROM, 4 KB RAM, and LQFP-100 package with validated stepper motor driver outputs and LCD segment drivers.
Technical Context
The S912ZVHY64F1VLQ implements the S12Z CPU core with 32 MHz bus speed and on-chip voltage regulator supporting 5–18 V input across -40°C to +105°C ambient. It embeds two independent physical layer transceivers: one ISO 11898-compliant CAN PHY and one LIN 2.2-compliant LIN PHY - both directly connected to internal protocol controllers without external transceiver components.
It integrates four dedicated stepper motor drivers with integrated stall detection logic and current sensing, plus a segment LCD controller supporting up to 40 segments × 4 commons. The device includes 10-bit 8-channel ADC, dual 16-bit timer modules (8 channels total), and 8-bit/16-bit PWM outputs mapped to GPIO pins for gauge needle control and backlight dimming.
Key Specifications
