S9S12VR64F2CLC Equivalent & Substitute Parts

Part Overview

The S9S12VR64F2CLC is a 16-bit embedded microcontroller from NXP USA Inc. belonging to the S12 MagniV series. This device integrates a 12V1 core processor operating at 25MHz with 64KB FLASH program memory, 512 bytes EEPROM, and 2KB RAM. The microcontroller features integrated connectivity options including IrDA, LINbus, SCI, and SPI interfaces, along with peripheral functions such as low-voltage detection (LVD), power-on reset (POR), pulse-width modulation (PWM), and watchdog timer (WDT). The device is packaged in a 32-LQFP (7x7mm) surface-mount configuration.

The S9S12VR64F2CLC carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing system support, maintenance, and component procurement when original inventory becomes unavailable.
