Overview
The M51923JFP#DD is a microcontroller unit manufactured by Renesas Electronics Corporation. It belongs to the M16C/60 series, featuring a 16-bit CPU architecture with a maximum operating frequency of 32 MHz. The device integrates 96 KB of program memory and 8 KB of RAM. Additional on-chip resources include 12 KB of data flash, nine 16-bit timer channels, twenty-seven 10-bit ADC channels, one 8-bit DAC, and an RTC. It supports CAN communication via one channel and includes Low Voltage Detect (LVD) or Programmable Voltage Detector (PVD) functionality. The component operates within a temperature range of -40°C to +85°C and is housed in an 80-lead PLQP package.
Feature Summary
- Integrates a 16-bit M16C/60 CPU core for efficient processing
- Includes extensive peripheral set with multiple timers, ADCs, and DAC
- Features built-in CAN interface for automotive and industrial networking
- Provides non-volatile data flash storage for parameter retention
Applications
- Automotive body electronics control modules
- Industrial motor control systems
- Consumer appliances requiring robust I/O capabilities
- General-purpose embedded control applications
Procurement Notes
Verify the specific suffix #DD against official Renesas documentation to confirm exact packaging and environmental compliance specifications. Confirm that the M16C/60 series remains suitable for your design as newer alternatives like the RX231 or RL78/G14 groups are recommended for new designs. Ensure compatibility with existing firmware development tools and compilers associated with this legacy architecture before procurement.
Selection Notes
Select this component when a proven 16-bit architecture with high I/O count and integrated analog peripherals is required. The M16C/60 series offers a balance of processing power and peripheral density suitable for complex control tasks. Consider the availability of long-term supply support given the product status. Evaluate if the 32 MHz speed and memory sizes meet the application's real-time processing demands without unnecessary overhead.
Part Context
This part is part of the M16C/5M and M16C/57 groups within the broader M16C family. These microcontrollers are designed for applications requiring reliable performance in harsh environments. The M16C/60 core provides a mature ecosystem with established development tools. While supported for existing customers, Renesas directs new designs toward more modern architectures for enhanced performance and efficiency.
Replacement Considerations
Renesas recommends the RX231 and RL78/G14 groups for new designs instead of the M16C/5M/57 series. These newer families offer improved performance, lower power consumption, and updated peripheral sets. Transitioning to these alternatives may require significant firmware re-engineering but ensures long-term supply chain stability and access to current technical support.
