Product details
Overview
R4F24248NFPV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2424 Group, featuring a 32 MHz max CPU clock, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and CPG (clock pulse generator). It targets industrial control panels and embedded motion controllers requiring deterministic real-time response and nonvolatile program storage.
For engineers reviewing the R4F24248NFPV datasheet, R4F24248NFPV pinout, R4F24248NFPV application, or R4F24248NFPV equivalent, this page delivers verified hardware specifications, validated package mapping to LQFP-100, confirmed pin functions per User's Manual Rev.5.00 (Sep 2012), and two field-tested alternative MCUs with documented functional alignment for H8S-based legacy system maintenance.
Technical Context
The R4F24248NFPV implements the H8S/2400 Series CPU core with advanced mode support, 24-bit address space, and dual operating modes (Normal/Advanced) controlled by MDCR and SYSCR registers. It integrates a programmable CPG supporting internal PLL multiplication and multiple clock sources (main oscillator, sub-oscillator, external clock input).
Peripheral subsystems include eight-channel TPU with PWM output capability, two independent SCI modules supporting asynchronous full-duplex communication at up to 2 Mbps, and a 16-channel interrupt controller with priority encoding and software standby release IRQ support - all mapped into fixed memory regions defined in the H8S/2424 memory map.
