Product details
Overview
R5F21334DNFP#10 from Renesas is a 16-bit R8C CPU core microcontroller with 16 KB flash ROM, 1 KB RAM, 32-pin LQFP package, and operating temperature range of -20°C to +85°C. It integrates UART0/UART2 (with I²C mode), 10-bit 12-channel ADC, four timers (RA/RB/RC/RE), watchdog timer, voltage detection, and on-chip oscillators for embedded control in consumer appliances and office equipment.
For engineers reviewing the R5F21334DNFP#10 datasheet, R5F21334DNFP#10 pinout, R5F21334DNFP#10 application, or R5F21334DNFP#10 equivalent, key selection considerations include its 16 KB flash capacity, 32-pin PLQP0032GB-A footprint, real-time clock capability via Timer RE, low-power wait/stop modes (down to 2.0 µA), and dual UART with I²C-bus support on UART2.
Technical Context
The R5F21334DNFP#10 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and 20-bit address space (1 Mbyte). Its interrupt system supports 69 vectors with 7 priority levels and includes dedicated key input interrupts (KI0–KI3) and external INT0–INT3 inputs.
Clock generation includes four independent circuits: XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled dividers (1/2/4/8/16) and usable in standard/wait/stop power modes.

FAQ
What is the maximum operating frequency of the R5F21334DNFP#10 and under what voltage conditions?
The R5F21334DNFP#10 operates at up to 20 MHz when supplied with VCC = 2.7–5.5 V. At reduced supply voltages (1.8–5.5 V), the maximum frequency is 5 MHz. These limits are defined by the R8C CPU core's timing specifications and ensure reliable instruction execution across the full operating voltage range.
Does the R5F21334DNFP#10 support I²C-bus communication, and if so, which peripheral implements it?
Yes, the R5F21334DNFP#10 supports I²C-bus communication via UART2, which includes dedicated I²C mode functionality. Pins P3_7 (SCL2) and P3_4/P3_5 (SDA2) serve as the I²C clock and data lines, with built-in bus collision detection and multiprocessor communication features enabled in this mode.
What are the real-time clock capabilities of the R5F21334DNFP#10, and how is it implemented?
The R5F21334DNFP#10 implements real-time clock (RTC) functionality using Timer RE, an 8-bit timer configured for calendar timekeeping (seconds, minutes, hours, days of week). It requires the 32 kHz XCIN/XCOUT crystal oscillator and operates independently in wait/stop modes, drawing only 3.5 µA or 2.0 µA respectively.
How many analog-to-digital converter channels does the R5F21334DNFP#10 have, and what is their resolution?
The R5F21334DNFP#10 integrates a single 10-bit successive-approximation ADC with 12 input channels (AN0–AN11). It includes sample-and-hold circuitry and supports sweep mode for automatic sequential conversion across selected channels, enabling efficient sensor data acquisition without CPU intervention.
What debug and programming interfaces are supported by the R5F21334DNFP#10?
The R5F21334DNFP#10 supports on-chip debug (OCD) via a dedicated serial interface, enabling full flash programming, breakpoint setting, and real-time variable inspection without external JTAG emulators. It also supports on-board flash rewrite during application runtime, simplifying field firmware updates and reducing test infrastructure costs.
