S9S12VR64F2CLF Equivalent & Substitute Parts

Part Overview

The S9S12VR64F2CLF 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 protocols, 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 48-pin LQFP surface-mount configuration.

The S9S12VR64F2CLF carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing system support, maintenance, and new design implementations where this microcontroller specification remains functionally required.

Substitute Part Grouping Explanation

Substitution of the S9S12VR64F2CLF is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must originate from NXP USA Inc. and belong to the S12 MagniV series to ensure architectural compatibility and instruction set alignment.
• Core Processor and Core Size: The 12V1 core processor and 16-bit architecture must remain constant to guarantee software compatibility and peripheral integration.
• Clock Speed: The 25MHz operating frequency must be maintained to preserve timing-dependent functionality and real-time performance characteristics.
• Memory Configuration: Program memory (64KB FLASH), EEPROM (512 x 8), and RAM (2K x 8) must match exactly to ensure code and data storage compatibility.
• Voltage Supply Range: The 3.13V ~ 5.5V supply voltage specification must be identical for power distribution and signal integrity.
• I/O Count and Connectivity: 28 I/O pins with IrDA, LINbus, SCI, and SPI connectivity must be preserved for interface compatibility.
• Peripheral Set: LVD, POR, PWM, and WDT functions must be present and functionally equivalent.
• Package and Mounting: The 48-LQFP (7x7) surface-mount package must remain unchanged for PCB layout compatibility.
• Compliance Standards: RoHS3 compliance and MSL rating (3, 168 Hours) must be maintained.

The S9S12VR64AF0CLF meets all these criteria and qualifies as a direct substitute.

Parameter Comparison
