It integrates dual power domains (VCC1/VCC2), 85 CMOS I/O ports, and supports industrial motor control, remote control signal reception, and HDMI CEC applications.

For engineers reviewing the R5F364AKNFB#10 datasheet, R5F364AKNFB#10 pinout, R5F364AKNFB#10 application, or R5F364AKNFB#10 equivalent, key selection criteria include its 100-pin LQFP package, three-phase inverter control capability, 26-channel 10-bit A/D converter with 1.72 µs conversion time, and dual-voltage external bus interface supporting 8/16-bit data width and up to 4 MB address expansion.

Technical Context

The R5F364AKNFB#10 implements the M16C/60 CPU core with hardware multiplier (16×16→32 bit) and multiply-accumulate instruction, enabling deterministic real-time motor control loops. Its memory architecture supports single-chip, memory expansion, and microprocessor modes with configurable bus timing (0–3 wait states) and four chip-select outputs.

Peripheral integration includes five 16-bit Timer A units (with PWM, encoder input, dead-time generation), six 16-bit Timer B units (pulse width/period measurement), two 8-bit D/A converters, CRC-CCITT/CRC-16 calculator, and dedicated CEC transceiver operating at 32 kHz - all mapped to a fixed 100-pin LQFP pinout with dual-power I/O banks.

FAQ

What is the operating temperature range for the R5F364AKNFB#10?

The R5F364AKNFB#10 is rated for -20°C to +85°C ambient operation, validated per Renesas specification R01DS0032EJ0200. This industrial-grade temperature range supports deployment in enclosed motor drives and consumer electronics enclosures without active cooling. The device uses on-chip voltage detection and EMI-hardened design to maintain stability across this full range.

Does the R5F364AKNFB#10 support in-system programming of its flash memory?

Yes, the R5F364AKNFB#10 supports full in-system programming of program ROM and data flash via its on-chip debug interface. The data flash endurance is rated at 10,000 erase/write cycles, while program ROM is rated for 1,000 cycles. R5F364AKNFB#10 includes ROM code protection and ID code check features to secure firmware during field updates.

How does the R5F364AKNFB#10 implement three-phase motor control?

The R5F364AKNFB#10 implements three-phase motor control using Timer A1, A2, A4, and Timer B2 with dedicated on-chip dead-time insertion logic. It provides U/V/W output pins directly driving gate drivers, eliminating external dead-time generators. The R5F364AKNFB#10 also supports encoder input via Timer A event counter mode for position feedback in closed-loop systems.

Can the R5F364AKNFB#10 operate with different supply voltages on VCC1 and VCC2?

Yes, the R5F364AKNFB#10 supports independent supply domains: VCC1 (2.7–5.5 V) powers the core and analog peripherals, while VCC2 (2.7 V to VCC1) powers the external bus interface. This allows interfacing with 3.3 V peripherals while maintaining 5 V-compatible I/O on VCC1 pins - a key feature confirmed in Table 1.6 of the R5F364AKNFB#10 datasheet.

What communication interfaces are available on the R5F364AKNFB#10?

The R5F364AKNFB#10 integrates UART0–UART2 and UART5–UART7 (6 total), two clock-synchronous serial I/O channels, one multi-master I²C-bus interface, and a dedicated CEC transceiver. All UARTs support both asynchronous and clock-synchronous modes, and the I²C interface includes N-channel open-drain SDA/SCL pins with arbitration support - fully documented in Table 1.2 of the R5F364AKNFB#10 datasheet.
