MC9S08JM32CLH

Microcontrollers Overview

The MC9S08JM32CLH is an 8-bit microcontroller from the NXP S08JM series, featuring a 48-MHz HCS08 CPU with a 24-MHz internal bus frequency. It integrates 32 KB of on-chip in-circuit programmable Flash memory and 4 KB of RAM. The device includes a USB 2.0 full-speed device controller with a dedicated transceiver, a 12-channel 12-bit ADC, an analog comparator, two SCI modules, two SPI modules, an IIC module, TPMs, and a keyboard interrupt module. It supports up to 51 GPIO pins and offers multiple power-saving modes including Wait and Stop.

Microcontrollers Feature Summary

• Integrated USB 2.0 full-speed device controller with dedicated transceiver
• 12-channel 12-bit analog-to-digital converter with automatic compare function
• Flexible timer/pulse-width modulator modules with input capture and output compare capabilities
• Comprehensive system protection including low-voltage detection and COP reset

Microcontrollers Applications

• USB-enabled consumer electronics
• Industrial control systems requiring analog signal processing
• Battery-powered devices utilizing low-power stop modes
• General-purpose embedded applications with serial communication needs

Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the LQFP-64 package. Confirm that the 32 KB Flash variant meets application requirements instead of the 60 KB version. Check for any recent lifecycle status updates or recommended replacement parts.

Microcontrollers Selection Notes

Select this component when USB connectivity is required alongside high-resolution analog acquisition. The 32 KB Flash size is suitable for moderate firmware complexity. Consider the 64-pin LQFP package for balanced pin count and board space. Evaluate the need for the integrated USB transceiver versus external solutions based on cost and design constraints.

Microcontrollers Part Context

This part belongs to the NXP S08JM family, designed for cost-sensitive applications requiring USB functionality. It shares architectural similarities with the MC9S08JM60 but offers reduced memory capacity. The family targets markets needing robust peripheral integration in a compact 8-bit MCU form factor.

Microcontrollers Replacement Considerations

MC9S08JM60CLH: Offers identical peripherals and pinout but with 60 KB Flash memory. Verify if the additional memory justifies potential cost differences.
