Product details
Overview
R5F10368ASP#V0 from Renesas is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller with 8 KB code flash, 512 B RAM, 1.8–5.5 V operation, and 31 DMIPS at 24 MHz-designed for battery-powered consumer electronics requiring HALT/STOP/SNOOZE power modes and integrated 8/10-bit A/D conversion.
For engineers reviewing the R5F10368ASP#V0 datasheet, R5F10368ASP#V0 pinout, R5F10368ASP#V0 application, or R5F10368ASP#V0 equivalent, key selection criteria include its 20-pin LSSOP-20 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.
Technical Context
The R5F10368ASP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 0.04167 µs minimum instruction execution time at 24 MHz using the high-speed on-chip oscillator. It supports HS/LS clock modes, 1 MB address space, and 4-channel 16-bit timer (TAU0) with PWM capability.
Its peripheral set excludes data flash, DMA, CRC, RAM guard, and SFR guard-features present in R5F102-series counterparts-while retaining UART0, CSI00, IICA0, 11-channel A/D converter (8/10-bit), and key interrupt support across 6 pins. The device operates in A-grade temperature range (–40°C to +85°C) and uses a single 1.8–5.5 V supply.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F10368ASP#V0?
The R5F10368ASP#V0 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, with an accuracy of ±5.0% over the full industrial temperature range (–40°C to +85°C). This specification eliminates the need for an external crystal in cost-sensitive applications while maintaining sufficient timing stability for UART communication and sensor sampling.
Does the R5F10368ASP#V0 include data flash memory?
No, the R5F10368ASP#V0 does not include data flash memory. As confirmed in the RL78/G12 datasheet section 1.3.1, R5F103-series devices omit the 2 KB data flash found in R5F102-series counterparts. This simplifies the memory map and reduces cost but requires external EEPROM or FRAM if non-volatile parameter storage is needed in the R5F10368ASP#V0 design.
How many serial communication interfaces does the R5F10368ASP#V0 support?
The R5F10368ASP#V0 supports three serial interfaces: one UART channel (UART0), one simplified SPI interface (CSI00), and one I²C-compatible interface (IICA0). Unlike the R5F10268ASP#V0, it does not include a second CSI or simplified I²C channel, nor does it support DMA-accelerated transfers-making it ideal for single-peripheral control tasks rather than complex multi-interface bridging.
What power-saving modes are available on the R5F10368ASP#V0?
The R5F10368ASP#V0 implements HALT, STOP, and SNOOZE low-power modes. HALT stops the CPU clock while preserving RAM and register contents; STOP disables all clocks except the low-speed on-chip oscillator (15 kHz); SNOOZE allows selected peripherals like UART or ADC to operate autonomously during STOP mode. These modes enable sub-μA standby current in battery-powered applications.
Is the R5F10368ASP#V0 pin-compatible with other RL78/G12 variants?
No, the R5F10368ASP#V0 is not pin-compatible with 24-pin or 30-pin RL78/G12 variants due to differing pin counts and layouts. Within the 20-pin LSSOP family, it shares the PLSP0020JB-A footprint with other R5F10x6x devices, but functional pin assignments differ between R5F102 and R5F103 series-for example, DMA and data flash pins are unconnected or repurposed in the R5F10368ASP#V0.
