It operates at 32 MHz (2.7–5.5 V), supports -40°C to +85°C industrial temperature range, and targets embedded control in audio/video equipment and industrial systems.
For engineers reviewing the R5F3650NDFB#30 datasheet, R5F3650NDFB#30 pinout, R5F3650NDFB#30 application, or R5F3650NDFB#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), CEC compliance for HDMI-adjacent devices, real-time clock with calendar function, and on-chip dead-time timer for inverter gate drive.
Technical Context
The R5F3650NDFB#30 implements the M16C/60 CPU core with 16×16-bit multiplier and multiply-accumulate instruction, enabling deterministic motor control loops. Its clock system integrates main/sub oscillators, 40 MHz ±10% high-speed on-chip oscillator, PLL frequency synthesizer, and selectable prescalers (1/2/4/8/16) for flexible timing generation.
Peripheral integration includes six UART/serial channels (UART0–2, UART5–7), multi-master I²C-bus interface, two remote control signal receivers (32 kHz operation), CRC-CCITT/CRC-16 calculator, and DMAC with four cycle-steal channels triggered by 43 sources - supporting concurrent serial, timer, and memory transfers without CPU intervention.
