Product details
Overview
R5F10366ASP#V5 from Renesas Electronics is a 20-pin LSSOP RL78/G12 16-bit microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It features 2 KB code flash, 256 B RAM, 10-bit A/D converter with 11 input channels, and operates from 1.8 V to 5.5 V with 63 μA/MHz active current. It delivers 31 DMIPS at 24 MHz and supports HALT/STOP/SNOOZE low-power modes - ideal for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10366ASP#V5 datasheet, R5F10366ASP#V5 pinout, R5F10366ASP#V5 application, or R5F10366ASP#V5 equivalent, key selection criteria include its 20-pin LSSOP package, absence of data flash memory, single UART channel, no DMA controller, and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C - critical for cost-sensitive, low-complexity timing and interface tasks.
Technical Context
The R5F10366ASP#V5 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling minimum instruction execution time of 0.04167 µs at 24 MHz using the high-speed on-chip oscillator. Its peripheral set includes one UART channel, one simplified SPI (CSI) channel, no I²C interface, and four 16-bit timer channels - all configured via fixed-function pins without peripheral I/O redirection (PIOR = 00H).
Power management integrates on-chip POR, 12-level voltage detector (LVD), and three low-power modes (HALT, STOP, SNOOZE), while analog capability centers on an 11-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor. The device lacks CRC, RAM guard, SFR guard, and data flash - distinguishing it from R5F102-series variants.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F10366ASP#V5?
The R5F10366ASP#V5 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 µs under this condition. The device also supports lower-frequency operation down to 1 MHz for ultra-low-power modes, maintaining full functionality across the 1.8–5.5 V supply range.
Does the R5F10366ASP#V5 include data flash memory?
No, the R5F10366ASP#V5 does not include data flash memory. This is a defining distinction from the R5F102-series counterparts (e.g., R5F10266ASP#V5), which integrate 2 KB of data flash. The R5F10366ASP#V5 relies solely on its 2 KB code flash for program storage and uses its 256 B RAM for runtime data - appropriate for applications where infrequent parameter storage is handled externally or via EEPROM emulation in code flash.
What serial communication interfaces are supported by the R5F10366ASP#V5?
The R5F10366ASP#V5 supports one UART channel (UART0), one simplified SPI (CSI) channel, and no built-in I²C interface. While pins P60 and P61 are labeled SCLA0 and SDAA0 in the datasheet, these functions are not implemented on R5F103-series devices per Section 1.3.1 and Table 1-1. The device also lacks DMA support for serial peripherals, requiring polled or interrupt-driven transfers.
What are the key differences between R5F10366ASP#V5 and R5F10266ASP#V5?
The R5F10366ASP#V5 omits data flash memory, DMA controller, CRC engine, RAM guard, and SFR guard - features present in the R5F10266ASP#V5. It also has looser high-speed oscillator accuracy (±5.0% vs. ±1.0%) and reduced RAM (256 B vs. 1.5 KB). These trade-offs reduce cost and complexity while retaining core RL78/G12 functionality for less demanding applications.
Is the R5F10366ASP#V5 suitable for industrial temperature ranges?
The R5F10366ASP#V5 is rated for TA = –40°C to +85°C and designated for consumer (A) and industrial (D) applications - not the extended +105°C grade (G). Its electrical specifications, including oscillator accuracy and voltage detector thresholds, are guaranteed only within the –40°C to +85°C range. For environments exceeding +85°C, Renesas recommends the R5F10366DSP#V5 (D-grade) or equivalent G-grade variants from other RL78 families.
