Product details
Overview
R4S24562NVFQV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2400 Series, designed for embedded control applications requiring integrated peripherals, deterministic real-time response, and industrial-grade reliability. It features a 33 MHz max CPU clock, 512 KB on-chip Flash memory, 32 KB RAM, 12-channel 16-bit TPU, 4-channel SCI, and 8-channel 10-bit ADC - deployed in motor control subsystems of HVAC systems.
For engineers reviewing the R4S24562NVFQV datasheet, R4S24562NVFQV pinout, R4S24562NVFQV application, or R4S24562NVFQV equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), and support for H8S/2400-series instruction set compatibility with legacy firmware migration paths.
Technical Context
The R4S24562NVFQV implements the H8S/2456 core architecture with advanced mode support, including 32-bit addressing capability and extended register file access. Its system controller integrates a programmable clock pulse generator (CPG) supporting multiple clock sources (crystal, external clock, PLL-derived), and a bus state controller (BSC) enabling configurable wait-state insertion for external memory interfacing.
Peripheral integration includes a 16-bit timer pulse unit (TPU) with input capture, output compare, PWM generation, and phase counting modes; four independent serial communication interfaces (SCI) supporting asynchronous, clock-synchronous, and smart card protocols; and an 8-channel 10-bit successive-approximation ADC with sample-and-hold and scan conversion capability.

FAQ
What is the maximum operating frequency of the R4S24562NVFQV?
The R4S24562NVFQV operates at a maximum CPU frequency of 33 MHz, delivering a 30.3 ns instruction cycle time. This frequency is achieved using the on-chip clock pulse generator (CPG) with PLL multiplication of an external crystal or clock source. The R4S24562NVFQV maintains timing compliance across its full −40°C to +85°C industrial temperature range without derating.
Does the R4S24562NVFQV support in-system programming via standard interfaces?
Yes, the R4S24562NVFQV supports in-system programming (ISP) through its on-chip debug interface compatible with Renesas E1 and E20 emulators. Programming is performed via the dedicated debug port (not SCI or other user peripherals), allowing secure Flash reprogramming without removing the device from the target board. The R4S24562NVFQV also supports ROM-based bootloader execution for field updates over SCI or CAN if implemented externally.
How many analog-to-digital converter channels does the R4S24562NVFQV integrate?
The R4S24562NVFQV integrates an 8-channel, 10-bit successive-approximation ADC with sample-and-hold capability. Channels AD0–AD7 are mapped to Port A pins PA0–PA7 and support hardware-triggered scan conversion with configurable sampling intervals. The ADC achieves ±1 LSB integral nonlinearity and supports both single-shot and continuous conversion modes - critical for synchronized sensor acquisition in the R4S24562NVFQV's target applications.
Is the R4S24562NVFQV pin-compatible with other members of the H8S/2456 family?
Yes, the R4S24562NVFQV is pin-compatible with the R4S2456 and R4S2456R variants in the same 128-pin LQFP package. All share identical pin assignments, electrical characteristics, and peripheral mapping. Differences lie in internal Flash configuration (e.g., boot area size) and minor revision-level errata fixes - not affecting mechanical or electrical interoperability. This allows direct substitution within existing R4S24562NVFQV-based designs.
What industrial certifications or quality grades apply to the R4S24562NVFQV?
The R4S24562NVFQV is classified as a Renesas "Standard" grade product, qualified for use in industrial robots, machine tools, test and measurement equipment, and factory automation systems. It meets AEC-Q100 stress testing requirements for temperature cycling and humidity exposure, and complies with RoHS Directive 2011/65/EU. The R4S24562NVFQV is not rated for automotive safety-critical applications or transportation-grade ("High Quality") use cases.
