Product details
Overview
R5F364AKNFA#U0 from Renesas Electronics is a 16-bit microcontroller (MCU) based on the M16C/60 Series CPU core with integrated flash memory, designed for embedded control in resource-constrained systems. It delivers 384 KB program ROM, 16 KB RAM, 31 KB data flash, and operates at 25 MHz with 40 ns minimum instruction execution time across 2.7–5.5 V supply. Its integrated peripherals-including 26-channel 10-bit A/D converter, dual 8-bit D/A converters, six UARTs, multi-master I²C, CEC interface, and three-phase motor control timers-support real-time control in audio/video and industrial equipment.
For engineers reviewing the R5F364AKNFA#U0 datasheet, R5F364AKNFA#U0 pinout, R5F364AKNFA#U0 application, or R5F364AKNFA#U0 equivalent, key selection considerations include its 100-pin QFP package (PRQP0100JD-B), -20°C to +85°C operating temperature, dual power supply (VCC1/VCC2), and support for external bus expansion up to 4 MB address space with selectable 8-/16-bit data width.
Technical Context
The R5F364AKNFA#U0 implements the M16C/60 Series CPU core with hardware multiplier (16×16→32 bit, MAC), 91 basic instructions, and two register banks. It supports three operating modes: single-chip, memory expansion, and microprocessor-enabling flexible system architecture from standalone control to external memory interfacing.
Its clock system integrates four independent sources: main crystal oscillator (XIN/XOUT), sub-crystal (XCIN/XCOUT), low-speed on-chip 125 kHz oscillator, and PLL frequency synthesizer-with programmable dividers (1/2/4/8/16), oscillation stop detection, and real-time clock capability. Voltage detection includes power-on reset and three configurable voltage detection points.
