Product details
Overview
R5F10367ASP#35 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 2 KB code flash, 256 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit TAU timer, UART, simplified SPI (CSI), and operates from 1.8 V to 5.5 V at –40°C to +85°C - ideal for battery-powered sensor nodes and appliance sub-systems.
For engineers reviewing the R5F10367ASP#35 datasheet, R5F10367ASP#35 pinout, R5F10367ASP#35 application, or R5F10367ASP#35 equivalent, key selection criteria include its 2 KB flash / 256 B RAM memory configuration, absence of data flash and DMA, TSSOP20/LSSOP20 package compatibility, and verified UART+CSI peripheral set for simple serial communication in space-constrained designs.
Technical Context
The R5F10367ASP#35 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.04167 µs at 24 MHz (high-speed on-chip oscillator) and 1 µs at 1 MHz (ultra-low-speed mode). It uses a single-supply 1.8–5.5 V rail and integrates HALT/STOP/SNOOZE low-power modes for dynamic power management.
Its peripheral set is defined by the R5F103 product variant: no data flash memory, no DMA controller, no CRC or RAM/SFR guard safety functions, and only one UART channel plus one simplified SPI (CSI) channel - distinguishing it from R5F102-series parts with enhanced peripherals and 2 KB data flash.

FAQ
What is the maximum operating frequency of the R5F10367ASP#35?
The R5F10367ASP#35 supports up to 24 MHz operation using its high-speed on-chip oscillator, delivering 31 DMIPS performance. When using an external crystal (X1/X2), maximum frequency is 20 MHz under 2.7–5.5 V supply or 8 MHz under 1.8–2.4 V supply - verified in the RL78/G12 datasheet Rev.2.50 Section 1.7.
Does the R5F10367ASP#35 include data flash memory?
No, the R5F10367ASP#35 does not include data flash memory. As confirmed in Section 1.3.1 of the RL78/G12 datasheet, only R5F102-series parts (e.g., R5F10267ASP#35) integrate 2 KB data flash; R5F103-series parts like R5F10367ASP#35 omit this feature to reduce cost and complexity.
Which serial interfaces are available on the R5F10367ASP#35?
The R5F10367ASP#35 provides one UART channel (RxD0/TxD0) and one simplified SPI (CSI00) channel. It does not support I²C communication or additional UART/CSI channels - a key distinction from R5F102-series variants, as documented in Section 1.3.3 and Table 1-1 of the datasheet.
What is the package type and pin count of the R5F10367ASP#35?
The R5F10367ASP#35 uses a 20-pin plastic LSSOP package (4.4 × 6.5 mm, 0.65-mm pitch), identified by the "SP" suffix and #35 packaging specification (tray for LSSOP20, tube for TSSOP20). Pin configuration matches the 20-pin RL78/G12 layout shown in Figure 1-1 and Section 1.4.1 of the datasheet.
Can the R5F10367ASP#35 operate from a 1.8 V supply?
Yes, the R5F10367ASP#35 is fully specified for 1.8 V to 5.5 V operation across its entire temperature range (–40°C to +85°C). At 1.8 V, it supports up to 8 MHz system clock (LS mode) and maintains full functionality including ADC, timers, and UART - per Section 1.1 and Table 1-1 of the RL78/G12 datasheet.
