Product details
Overview
R5F35636DFF#U0 from Renesas is a 16-bit flash microcontroller in the M16C/56D Group, featuring an M16C/60 Series CPU core, 128 KB program ROM 1, 16 KB RAM, and 12 KB data flash. It operates at up to 32 MHz (3.0–5.5 V) with 55 CMOS I/O pins, 4-channel DMAC, and integrated peripherals including UARTs, timers, A/D converters, and I²C. It targets industrial control and embedded systems requiring deterministic real-time response.
For engineers reviewing the R5F35636DFF#U0 datasheet, R5F35636DFF#U0 pinout, R5F35636DFF#U0 application, or R5F35636DFF#U0 equivalent, key selection criteria include its 64-pin LQFP package, absence of CAN interface (distinguishing it from M16C/5LD variants), 10-bit A/D with 16 channels, and support for three-phase motor control timing functions.
Technical Context
The R5F35636DFF#U0 implements the M16C/60 Series CPU core with 91 basic instructions, 16×16-bit multiplier, and multiply-accumulate unit. Its memory architecture includes separate program ROM 1 (128 KB), program ROM 2, and data flash (12 KB), all accessible via on-chip flash rewrite capability and ROM code protection.
Peripherals are tightly coupled to the CPU via dedicated interrupt vectors (70 total) and DMA trigger sources (40). The timer system supports three-phase motor control using Timer A1/A2/A4 and Timer B2, with on-chip dead time generation, while the A/D converter provides 10-bit resolution across 16 analog input channels plus 4 additional channels in the A/D1 circuit.
