It operates at up to 80 MHz and targets industrial motor control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the R5F72146BDFA#V1 datasheet, R5F72146BDFA#V1 pinout, R5F72146BDFA#V1 application, or R5F72146BDFA#V1 equivalent, key selection criteria include CAN interface support, Flash endurance (100K write/erase cycles), operating temperature range (−40°C to +85°C), and compliance with IEC 60730 Class B functional safety requirements for self-test capability.
Technical Context
The R5F72146BDFA#V1 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction. It integrates a Clock Pulse Generator (CPG) supporting PLL-based clock synthesis, multiple low-power modes (HALT, STOP, and SNOOZE), and a Data Transfer Controller (DTC) enabling autonomous peripheral-to-memory transfers without CPU intervention.
Its system architecture includes a Bus State Controller (BSC) for external bus interfacing, an Interrupt Controller (INTC) with 128 vector entries and priority levels, and a Watchdog Timer (WDT) with windowed operation mode. The device supports boot from internal Flash or external ROM via configurable boot pins and includes hardware CRC calculation units for firmware integrity verification.

The R5F72146BDFA#V1 integrates CAN 2.0B (with 32 message objects), four Serial Communication Interfaces (SCI) supporting UART/LIN protocols, two Inter-Integrated Circuit (I²C) buses, and a Data Transfer Controller (DTC) for autonomous peripheral data movement. These interfaces are electrically and logically verified in the R5F72146BDFA#V1 pin assignment and peripheral specification sections of the Hardware User's Manual, enabling concurrent multi-protocol communication in complex embedded systems such as automotive body controllers and industrial PLCs.
Is the R5F72146BDFA#V1 pin-compatible with other SH7214 Group devices?
Yes, the R5F72146BDFA#V1 is pin-compatible with other members of the SH7214 Group in the same 144-pin LQFP package, including R5F72145BDFA#V1 and R5F72147BDFA#V1. Pin compatibility is confirmed in Section 1.3 "Pin Assignment" of the SH7214 Group Hardware User's Manual, which shows identical pin functions across these variants. This allows hardware reuse across product families while scaling Flash, RAM, and peripheral sets - a design benefit explicitly leveraged in the R5F72146BDFA#V1's shared footprint strategy.
What development tools are officially supported for the R5F72146BDFA#V1?
