Renesas R5F363AMDFA#U0

Overview

R5F363AMDFA#U0 from Renesas Electronics is a 16-bit M16C/60 Series CPU core microcontroller with 512 KB program flash, 16 KB RAM, and 31 KB data flash, operating at up to 20 MHz (VCC1 = 2.7–5.5 V). It integrates A/D (10-bit × 26 ch), D/A (8-bit × 2), UART (6 channels), I²C, CEC, PWM, real-time clock, and three-phase motor control timers - deployed in industrial HMI, audio subsystems, and consumer appliance main control units.

For engineers reviewing the R5F363AMDFA#U0 datasheet, R5F363AMDFA#U0 pinout, R5F363AMDFA#U0 application, or R5F363AMDFA#U0 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade, 100-pin QFP (PRQP0100JD-B) package with dual power supply (VCC1/VCC2), integrated CEC for HDMI-CEC compliance, and on-chip debug support for flash rewrite and address match interrupts.

Technical Context

The R5F363AMDFA#U0 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction, enabling efficient signal processing in embedded control loops. Its memory architecture supports 1 MB address space (expandable to 4 MB) with external bus interface featuring 4 chip selects, programmable wait states, and selectable 8/16-bit data bus width.

Peripherals include Timer A (5×16-bit) with PWM, encoder input, and dead-time generation; Timer B (6×16-bit) with pulse width/period measurement; and dedicated CEC transceiver (32 kHz operation) compliant with HDMI CEC standard. Real-time clock provides calendar-based timekeeping with automatic correction and 0.25/0.5 s periodic interrupts.

FAQ

What is the operating temperature range specified for the R5F363AMDFA#U0?

The R5F363AMDFA#U0 is rated for an industrial operating temperature range of -40°C to +85°C. This specification is confirmed in Table 1.5 of the R01DS0033EJ0220 datasheet, where the "D" suffix denotes the extended temperature grade. The device maintains full electrical performance across this range without derating.

Does the R5F363AMDFA#U0 support HDMI Consumer Electronics Control (CEC)?

Yes, the R5F363AMDFA#U0 includes a dedicated CEC transceiver function on pin P8_5/NMI/SD/CEC, operating at 32 kHz. As documented in Tables 1.1–1.4 and Figure 1.4, it supports CEC transmit/receive, arbitration lost detection, and automatic ACK output - fully compliant with HDMI CEC protocol requirements.

What package type is used by the R5F363AMDFA#U0?

The R5F363AMDFA#U0 uses the PRQP0100JD-B package - a 100-pin plastic quad flat package (QFP) with 0.65 mm pitch and 20 × 20 mm body size. This is explicitly stated in Table 1.5 and Figure 1.6 of the R01DS0033EJ0220 datasheet, and corresponds to the legacy code 100P6F-A.

How much flash memory does the R5F363AMDFA#U0 contain, and what is its endurance?

The R5F363AMDFA#U0 contains 512 KB of program flash memory and 31 KB of data flash memory. Per Table 1.1, program flash endurance is 1,000 write/erase cycles, while data flash endurance is 10,000 cycles - enabling robust field firmware updates and persistent parameter storage.

Does the R5F363AMDFA#U0 support three-phase motor control functions?

Yes, the R5F363AMDFA#U0 supports hardware three-phase inverter control using Timer A1, A2, A4 and Timer B2, including on-chip dead-time timer functionality. This is confirmed in Table 1.2 under "Three-phase motor control timer functions" and in the block diagram (Figure 1.4), enabling direct gate driver interfacing without external logic.
