Product details
Overview
R5F3650ECDFB#10 from Renesas is a 16-bit M16C/60 Series CPU core microcontroller with 256 KB program ROM, 20 KB RAM, and 4 KB × 2 data flash, operating at up to 32 MHz (VCC1 = 2.7–5.5 V). It integrates 26-channel 10-bit A/D converter (1.72 µs conversion), dual 8-bit D/A converters, CEC interface for HDMI control, and three-phase motor control timers - deployed in industrial HMI panels and consumer audio/video subsystems.
For engineers reviewing the R5F3650ECDFB#10 datasheet, R5F3650ECDFB#10 pinout, R5F3650ECDFB#10 application, or R5F3650ECDFB#10 equivalent, key selection criteria include its 100-pin LQFP (PLQP0100KB-A) package, -40°C to +85°C industrial temperature grade, on-chip PLL and real-time clock, and support for UART/I²C/CEC/remote control signal reception at 32 kHz.
Technical Context
The R5F3650ECDFB#10 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction, executing instructions in as little as 31.25 ns at 32 MHz. Its memory architecture supports 1 MB address space (expandable to 4 MB) via external bus with 0–8 wait states, separate/multiplexed bus modes, and 8-/16-bit data width selection.
Peripheral integration includes five 16-bit Timer A units (PWM, encoder input, programmable output), six 16-bit Timer B units (pulse width/period measurement), on-chip dead-time timer for three-phase inverter control, and dual remote control receivers with 4-wave pattern matching and 6-byte buffer (one channel).
