Product details
Overview
R5F3650NCNFB#30 from Renesas Electronics is a 16-bit flash microcontroller in the M16C/65C Group, featuring an M16C/60 Series CPU core with 16×16-bit multiplier, 512 KB program ROM, 47 KB RAM, and 4 KB ×2 data flash. It operates at up to 32 MHz (2.7–5.5 V), integrates 26-channel 10-bit A/D converter (1.72 µs conversion), dual 8-bit D/A converters, and supports three-phase motor control via on-chip dead-time timers - deployed in industrial HMI panels and consumer audio subsystems.
For engineers reviewing the R5F3650NCNFB#30 datasheet, R5F3650NCNFB#30 pinout, R5F3650NCNFB#30 application, or R5F3650NCNFB#30 equivalent, key selection considerations include its 100-pin LQFP (PLQP0100KB-A) package, CEC interface compliance for HDMI-CEC remote control, real-time clock with calendar functions, and support for external bus expansion up to 4 MB address space.
Technical Context
The R5F3650NCNFB#30 implements a single-chip/microprocessor/external memory expansion mode architecture with five independent clock sources: main crystal (XIN/XOUT), sub-crystal (XCIN/XCOUT), 125 kHz on-chip oscillator, 40 MHz ±5% high-speed on-chip oscillator, and PLL frequency synthesizer. Its interrupt system delivers 70 vectors across 13 external inputs (including NMI, INT×8, key input×4) with seven priority levels.
Peripheral integration includes six UART channels (UART0–UART2, UART5–UART7), two clock-synchronous serial I/O interfaces, multi-master I²C-bus, CEC transceiver (32 kHz operation), and a CRC calculator compliant with both CRC-CCITT and CRC-16 standards - all coordinated by a 4-channel DMAC supporting cycle-steal transfers triggered by 43 sources.
