MC9S08SH8MSC

Overview

The MC9S08SH8MSC is an 8-bit microcontroller from the S08 family, manufactured by NXP Semiconductors (formerly Freescale Semiconductor). It features an HCS08 core operating at a maximum frequency of 40 MHz. The device includes 4 KB of flash memory and 256 bytes of RAM. It is housed in an 8-SOIC package with a width of 3.90 mm. The unit supports I2C, LINbus, SCI, and SPI interfaces. Peripheral functions include LCD, LVD, POR, PWM, and WDT. It has 5 I/O lines and operates within a temperature range of -40°C to 125°C.

Feature Summary

• Integrated support for LINbus communication protocols alongside standard serial interfaces
• Built-in low-voltage detection and power-on reset capabilities for system reliability
• Configurable pulse-width modulation and watchdog timer peripherals

Applications

• Automotive body electronics modules requiring LINbus connectivity
• Battery-powered handheld devices utilizing segment LCD drivers
• General-purpose control systems needing robust voltage monitoring

Procurement Notes

Verify the specific suffix MSC against official NXP documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding the 8-SOIC footprint. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit components.

Selection Notes

Select this component when a compact 8-pin solution is required for automotive or industrial applications. The inclusion of LINbus hardware simplifies network integration compared to software-only implementations. Consider the extended temperature range if the environment exceeds standard commercial limits. Evaluate pin count requirements carefully as the 8-SOIC limits available I/O resources.

Part Context

This MCU belongs to the S08 SH series, designed for cost-effective applications with EEPROM and LIN capabilities. It utilizes the HCS08 core architecture, providing efficient code execution for embedded control tasks. The series targets markets such as automotive body electronics and consumer appliances where small form factors are critical.

Replacement Considerations

Check for direct substitutes within the MC9S08SH8 family that may offer different package options or memory configurations. Verify pin-to-pin compatibility before replacing units in existing assemblies.
