Product details
Overview
R5F52104BDFL#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (8 channels), and real-time clock with deep software standby support. It targets industrial control panels requiring deterministic timing, low-power operation, and IEC60730-compliant safety functions.
For engineers reviewing the R5F52104BDFL#30 datasheet, R5F52104BDFL#30 pinout, R5F52104BDFL#30 application, or R5F52104BDFL#30 equivalent, key selection criteria include its 48-pin LQFP package, −40°C to +85°C temperature grade, integrated ELC for event-driven peripheral coordination, and hardware-assisted CRC calculation for firmware integrity verification.
Technical Context
The R5F52104BDFL#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its memory subsystem includes zero-wait-state 50-MHz flash access and SRAM, plus dedicated 8-KB data flash with 100,000 erase/program cycles and CPU-transparent operation.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Multi-function Pin Controller (MPC) allows flexible I/O function assignment across 34 general-purpose pins. The device supports four low-power modes, including deep software standby with RTC active.
