For engineers reviewing the R5F56604ADFN#10 datasheet, R5F56604ADFN#10 pinout, R5F56604ADFN#10 application, or R5F56604ADFN#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interfaces, 2.7–5.5 V supply range, –40°C to +85°C temperature grade (D-version), and full peripheral set including MTU3a timers, ELC event linking, and dual-channel 12-bit D/A output usable as comparator reference.

Technical Context

The R5F56604ADFN#10 implements the RXv3 CPU core with 113 instructions, 16 general-purpose 32-bit registers, and hardware multiplier/divider. Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and ADCLK (60 MHz).

Peripheral integration includes CAN FD compliant with ISO 11898-1:2015, 13 SCI channels supporting asynchronous, SPI-like, and I²C-like modes, two RIIC interfaces (400 kbps fast-mode), one RSPId (30 Mbps), 24-channel S12ADH A/D converter with self-diagnosis and disconnection detection, and four CMPC analog comparators. The ELC enables interrupt-free inter-module triggering, while the Trusted Memory (TM) function protects code flash against unauthorized read access.
