Product details
Overview
R5F10369ASP#V5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive consumer and industrial embedded control. It features 12 KB code flash, 768 B RAM, 10-bit 8-channel ADC, single UART, one simplified SPI (CSI), and operates from 1.8 V to 5.5 V with HALT/STOP/SNOOZE low-power modes - deployed in battery-powered sensor nodes and appliance control panels.
For engineers reviewing the R5F10369ASP#V5 datasheet, R5F10369ASP#V5 pinout, R5F10369ASP#V5 application, or R5F10369ASP#V5 equivalent, key selection criteria include its 20-pin LSSOP package, absence of data flash memory, -40°C to +85°C temperature grade (A), lack of DMA and safety functions (CRC/SFR guard), and verified 1-channel UART + 1-channel CSI peripheral configuration.
Technical Context
The R5F10369ASP#V5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and supports instruction execution times from 0.04167 µs (@24 MHz on-chip oscillator) to 1 µs (@1 MHz). Its clock system integrates a high-speed on-chip oscillator (1–24 MHz, ±5% accuracy over –40°C to +85°C) and a 15 kHz low-speed on-chip oscillator for watchdog timing.
Peripheral integration includes a 16-bit timer array (TAU0) with 4 channels, 12-bit interval timer, window watchdog timer, on-chip power-on-reset and voltage detector (12-level selectable), and key interrupt support across 6 pins. It lacks DMA, data flash, CRC engine, and SFR/RAM guard - distinguishing it from R5F102-series counterparts.

FAQ
What is the maximum operating frequency of the R5F10369ASP#V5?
The R5F10369ASP#V5 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. When using an external crystal (X1/X2), the maximum main system clock is 20 MHz at VDD ≥ 2.7 V or 8 MHz at VDD = 1.8–2.4 V. All timing specifications in the datasheet assume operation within these validated limits.
Does the R5F10369ASP#V5 include data flash memory?
No, the R5F10369ASP#V5 does not include data flash memory. This is a defining distinction from the R5F102xx series. The R5F10369ASP#V5 provides only 12 KB of code flash memory and 768 B of RAM. Non-volatile data storage must be implemented externally or via emulated EEPROM in code flash.
What are the supported low-power modes for the R5F10369ASP#V5?
The R5F10369ASP#V5 supports HALT, STOP, and SNOOZE low-power modes. HALT stops the CPU while keeping peripherals active; STOP disables the system clock entirely for minimal current draw; SNOOZE allows selected peripherals (e.g., UART, ADC) to operate while the CPU sleeps. Typical STOP mode current is 0.52 µA at 3.3 V and 25°C.
Can the R5F10369ASP#V5 drive a piezoelectric buzzer directly?
Yes, the R5F10369ASP#V5 can drive a piezoelectric buzzer directly using its PCLBUZ0 (P10) and PCLBUZ1 (P15, not present on 20-pin variants) outputs. P10 supports programmable frequency output from 2.44 kHz to 10 MHz, enabling tone generation without external drivers - confirmed in the RL78/G12 User's Manual Section 6.10.
Is the R5F10369ASP#V5 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10369ASP#V5 shares identical pinout and package (20-pin LSSOP) with all other R5F103xxASP#V5 and R5F102xxASP#V5 variants. However, peripheral availability differs: R5F10369ASP#V5 lacks DMA, data flash, CRC, and SFR guard found in R5F102xx parts - firmware must account for these functional absences.
