S9S12G48F0CLF

Product Overview

The S9S12G48F0CLF from NXP USA Inc. is a 16-bit HCS12 microcontroller built around the 12V1 core and operates at 25 MHz. It provides 48 KB of FLASH program memory, 4 KB of RAM, and 1.5 KB of EEPROM in a 48-LQFP surface-mount package. The device supports 3.13 V to 5.5 V supply, 40 I/O pins, and an internal oscillator. On-chip connectivity includes CANbus, LINbus, SCI, SPI, and IrDA, while peripherals include PWM, watchdog timer, power-on reset, and low voltage detection.

Key Features

• 16-bit HCS12 12V1 core operating at 25 MHz with 48 KB FLASH, 4 KB RAM, and 1.5 KB EEPROM.
• 40 I/O pins and 12 x 10-bit analog-to-digital conversion support sensor and signal measurement.
• Integrated serial and bus interfaces: CANbus, LINbus, SCI, SPI, and IrDA.
• On-chip PWM, watchdog timer, power-on reset, and low voltage detection support control and supervision functions.
• Operates from 3.13 V to 5.5 V supply with an internal oscillator.
• Surface-mount 48-LQFP (7x7) package rated for -40°C to 85°C ambient temperature.

Applications

• Embedded control systems that require bus communication through CANbus or LINbus.
• Embedded devices operating from 3.13 V to 5.5 V with PWM outputs.
• Instrumentation and measurement products that use 12 x 10-bit analog-to-digital conversion and serial interfaces such as SPI or SCI.

Design & Procurement Notes

Design considerations include matching the 48 KB FLASH, 4 KB RAM, and 1.5 KB EEPROM to firmware and nonvolatile data needs, while allocating the 40 I/O pins among control, communication, and analog inputs. The 48-LQFP (7x7) surface-mount package and -40°C to 85°C ambient rating should be reviewed for board layout, thermal behavior, and environmental exposure. Verify that the 3.13 V to 5.5 V supply, internal oscillator, CANbus, LINbus, SCI, SPI, IrDA, PWM, watchdog, power-on reset, and low voltage detection features align with the system architecture before selection.
