M37516F8HP#U2

Microcontrollers Overview

The M37516F8HP#U2 is a member of the M37500MC Group, a 16-bit microcontroller series based on the M37500 CPU core. This specific component integrates 16KB of mask ROM for program storage and 512 bytes of RAM for data handling. It operates within a voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 8MHz. The device features multiple timer channels, serial communication interfaces, and analog-to-digital conversion capabilities, packaged in a 64-pin LFQFP format suitable for industrial and automotive environments.

• Industrial motor control applications
• Factory automation equipment controllers

Microcontrollers Procurement Notes

Verify the exact ordering code including the suffix #U2 to ensure correct package and temperature grade alignment. Confirm that the mask ROM content matches the required firmware, as it is non-user-programmable. Check current lifecycle status, as older M37500 series parts may be subject to obsolescence notices or limited availability. Ensure design-in compatibility with existing 5V logic levels and pin configurations.

Microcontrollers Selection Notes

Select this part when a dedicated 16-bit MCU with fixed firmware requirements is needed for cost-sensitive automotive or industrial designs. Compare against the R8C/RX families if programmable flash memory or higher performance is required. Consider the 64-pin LFQFP footprint constraints and the 8MHz speed limit relative to system timing needs. Evaluate power management requirements against the available operating modes.

Microcontrollers Part Context

This component belongs to the Renesas M37500MC family, a long-established line of 16-bit microcontrollers widely used in automotive and industrial sectors. The M37516 variant specifically denotes the 16KB ROM capacity. While newer architectures like RL78 and RX are recommended for new designs, the M37500 series remains supported for legacy maintenance and specific high-reliability applications where its proven track record is valued.

Microcontrollers Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary M37500 architecture. Review Renesas documentation for migration guides to the RL78/F1x or RH850 families for modern equivalents. Verify functional equivalence regarding peripheral sets and interrupt structures before substituting with other 16-bit MCUs.
