It operates at 3.3 V supply voltage and supports industrial temperature range (−40°C to +85°C), targeting real-time control in motor drive and factory automation systems.
For engineers reviewing the R5F61668RN50BGV#GZ datasheet, R5F61668RN50BGV#GZ pinout, R5F61668RN50BGV#GZ application, or R5F61668RN50BGV#GZ equivalent, this page delivers verified technical context, package mapping, functional pin definitions, and validated alternative options for embedded control design and BOM continuity planning.
Technical Context
The R5F61668RN50BGV#GZ implements the H8SX CPU core with three operating modes (Normal, Middle, Advanced) and supports 32-bit addressing up to 4 GB. It integrates a Clock Pulse Generator (CPG) with PLL for internal clock synthesis and a Bus State Controller (BSC) enabling flexible external bus interface timing.
Peripheral integration includes a 16-bit Timer Pulse Unit (TPU) with 16 channels, four Serial Communications Interfaces (SCI) supporting asynchronous and clock-synchronous modes, and a Data Transfer Controller (DTC) that offloads CPU during memory-to-peripheral transfers without interrupt overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8SX 32-bit CISC architecture with 50 MHz max operation - enables deterministic real-time instruction execution for closed-loop control. |
| Memory | 1 MB on-chip Flash + 64 KB RAM - sufficient for complex firmware with bootloader, safety monitoring, and field-upgradable code. |
| Supply Voltage | 3.3 V ±0.3 V - compatible with standard industrial LDOs and eliminates need for level-shifting with 3.3 V I/O peripherals. |
| Operating Temp | −40°C to +85°C - qualified for use in uncontrolled industrial enclosures and motor control cabinets. |
| Package | 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch) - supports automated SMT assembly and thermal dissipation up to 1.5 W. |
