Product details
Overview
R5F3640ECDFB#30 from Renesas Electronics is a 16-bit flash microcontroller (MCU) based on the M16C/60 Series CPU core, featuring 256 KB program ROM 1, 16 KB RAM, and 20 KB data flash. It operates at up to 25 MHz with 40 ns minimum instruction execution time (VCC1 = VCC2 = 2.7–5.5 V), integrates a 16×16-bit multiplier and multiply-accumulate capability, and supports single-chip, memory expansion, and microprocessor operating modes. It targets embedded control in industrial equipment and consumer audio/video systems.
For engineers reviewing the R5F3640ECDFB#30 datasheet, R5F3640ECDFB#30 pinout, R5F3640ECDFB#30 application, or R5F3640ECDFB#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), -40°C to +85°C operating temperature range (D-version), integrated three-phase motor control timers, CEC transceiver for HDMI-CEC compliance, and dual-voltage bus interface (VCC1/VCC2).
Technical Context
The R5F3640ECDFB#30 implements the M16C/60 Series CPU core with two register banks, 20-bit program counter, and 11-bit flag register supporting interrupt priority levels 0–7. Its memory architecture provides 1 MB base address space expandable to 4 MB via memory area expansion, with separate VCC1 (core/analog) and VCC2 (bus I/O) power domains enabling mixed-voltage external bus interfacing.
Peripheral integration includes five 16-bit Timer A units (with PWM, encoder input, and programmable output), six 16-bit Timer B units (supporting pulse width/period measurement and three-phase inverter control), dual 8-bit D/A converters, 26-channel 10-bit A/D converter with sample-and-hold, multi-master I²C-bus interface, seven UART/SIO channels, and dedicated CEC transmit/receive circuitry operating at 32 kHz.

FAQ
What is the operating temperature range for the R5F3640ECDFB#30?
The R5F3640ECDFB#30 is rated for -40°C to +85°C operation (D-version). This extended industrial temperature range ensures reliable performance in demanding environments such as factory automation controls, outdoor kiosks, and automotive cabin electronics where ambient temperatures fluctuate widely. The specification is validated per Renesas' qualification standards and applies across all operating modes and peripheral configurations.
Does the R5F3640ECDFB#30 support HDMI-CEC functionality?
Yes, the R5F3640ECDFB#30 includes dedicated CEC transmit/receive circuitry compliant with HDMI CEC specifications. It features automatic ACK output, arbitration loss detection, and 32 kHz operation-enabling seamless integration into HDMI-connected audio/video products without external protocol translators. The CEC function is accessible via the shared P8_5 pin and requires no CPU intervention for basic command transmission or reception.
What package type is used for the R5F3640ECDFB#30?
The R5F3640ECDFB#30 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch). This RoHS-compliant package supports standard surface-mount assembly processes and provides mechanical stability for high-vibration industrial applications. Pin compatibility with the QFP variant (PRQP0100JD-B) is limited to signal mapping-not physical footprint-due to differing lead form and thermal pad design.
How much internal memory does the R5F3640ECDFB#30 have?
The R5F3640ECDFB#30 contains 256 KB of program ROM 1, 16 KB of RAM, and 20 KB of data flash memory. The data flash supports 10,000 erase/write cycles and is used for non-volatile parameter storage, while program ROM 1 holds application firmware. Memory organization follows a fixed map: RAM starts at 00400h, data flash occupies 0E000h–0FFFFh, and program ROM 1 resides in the upper 64 KB (F0000h–FFFFFh).
Can the R5F3640ECDFB#30 perform three-phase motor control?
Yes, the R5F3640ECDFB#30 integrates hardware timers (TA1, TA2, TA4, TB2) and an on-chip dead-time timer specifically for three-phase inverter control. These peripherals generate complementary PWM outputs with programmable dead time, support space-vector modulation, and accept hall sensor or encoder feedback directly-eliminating the need for external gate driver logic or FPGA-based timing generators in BLDC or PMSM motor applications.
