Product details
Overview
R5F52205BDFL#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (49 DMIPS), featuring 128 KB on-chip flash, 8 KB SRAM, 8 KB data flash, 12-bit A/D converter (1.56 µs conversion), and integrated RTC with leap-year support. It targets industrial control, sensor interface, and IEC60730-compliant appliance applications.
For engineers reviewing the R5F52205BDFL#30 datasheet, R5F52205BDFL#30 pinout, R5F52205BDFL#30 application, or R5F52205BDFL#30 equivalent, key selection considerations include its 48-pin LQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade (D version), 8-channel 12-bit ADC, ELC event-driven peripheral activation, and IEC60730 self-diagnostic features for functional safety compliance.
Technical Context
The R5F52205BDFL#30 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32 multiplication. Its memory subsystem includes zero-wait-state 128 KB flash (32 MHz operation) and 8 KB SRAM, both accessible at full CPU speed.
Peripherals are orchestrated via the Event Link Controller (ELC), which routes 46 event signals directly to modules without CPU intervention, enabling low-power operation and deterministic timing. The MCU supports IEC60730 Class B compliance through hardware-assisted RAM testing, A/D disconnection detection, clock accuracy measurement (CAC), and independent watchdog timer (IWDT) with dedicated 125 kHz oscillator.
