S9S12ZVLS3F0MFMR

Product Overview

The NXP USA Inc. S9S12ZVLS3F0MFMR is a 16-bit microcontroller based on the S12Z core and operates at 32 MHz. It provides 32KB (32K x 8) FLASH program memory, 1K x 8 RAM, and 128 x 8 EEPROM. The device includes 19 I/O pins, six 10-bit A/D inputs, and serial connectivity options including I2C, IrDA, LINbus, SCI, SPI, and UART/USART. On-chip peripherals include PWM, a watchdog timer, power-on reset, and low-voltage detect. It is housed in a 32-HVQFN (5x5) package with an exposed pad and wettable flank surface-mount construction, and it is specified for operation from 5.5 V to 18 V across a temperature range of -40°C to 125°C.

Design & Procurement Notes

Designers should compare the 5.5 V to 18 V supply range and -40°C to 125°C operating temperature with the target system environment. The 19 I/O pins, six 10-bit A/D inputs, and the serial interfaces should be checked against the number of external signals and communication links required by the design. The 32KB FLASH, 1K x 8 RAM, and 128 x 8 EEPROM should be evaluated against firmware size, runtime data, and configuration storage needs. The 32-HVQFN (5x5) exposed-pad package and wettable flank surface-mount construction require attention to PCB footprint and assembly process compatibility.
