Product details
Overview
R5F3650TDFB#10 from Renesas Electronics is a 16-bit M16C/60 Series CPU core microcontroller with 768 KB program flash, 16 KB RAM, and 47 KB data flash, operating at up to 32 MHz (VCC1 = 2.7–5.5 V). It integrates dual A/D converters (10-bit × 26 channels, 1.72 µs conversion), dual D/A converters (8-bit × 2), CEC interface for HDMI control, and three-phase motor control timers - deployed in industrial HMI panels requiring deterministic real-time I/O and embedded motor drive coordination.
For engineers reviewing the R5F3650TDFB#10 datasheet, R5F3650TDFB#10 pinout, R5F3650TDFB#10 application, or R5F3650TDFB#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 RTC, and support for CEC, multi-master I²C, and UART/SIM serial interfaces in resource-constrained embedded systems.
Technical Context
The R5F3650TDFB#10 implements the M16C/60 CPU core with 91 basic instructions and a dedicated 16×16-bit multiplier for high-speed arithmetic. Its memory architecture supports 1 MB address space (expandable to 4 MB) via external bus interface with configurable wait states, separate/multiplexed bus modes, and 8-/16-bit data width selection.
Peripheral integration includes six 16-bit Timer B units for pulse period/width measurement and three-phase inverter control, five 16-bit Timer A units with PWM and encoder input capability, and dual remote control signal receivers operating at 32 kHz with 4-wave pattern matching - enabling direct IR remote decoding without external logic.
