Product details
Overview
R5F10368ASP#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 8 KB code flash, 512 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit TAU timer, UART, 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 control panels.
For engineers reviewing the R5F10368ASP#V5 datasheet, R5F10368ASP#V5 pinout, R5F10368ASP#V5 application, or R5F10368ASP#V5 equivalent, key selection criteria include its 8 KB flash / 512 B RAM configuration, absence of data flash and DMA, 1-channel UART + 1-channel CSI interface set, and LSSOP-20 package with 0.65-mm pitch for compact PCB layout.
Technical Context
The R5F10368ASP#V5 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 MB address space. It uses a dedicated low-speed on-chip oscillator (15 kHz) for watchdog operation and supports HALT/STOP/SNOOZE low-power modes.
Its peripheral set excludes data flash memory and DMA controller - distinguishing it from R5F102xx variants - and integrates only one simplified I²C-compatible interface (IICA0), one UART channel (UART0), and one simplified SPI channel (CSI00), all mapped to fixed pins without peripheral I/O redirection in default PIOR=00H configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10268ASP#V5 | Includes 2 KB data flash and DMA controller; same 8 KB code flash, 512 B RAM, LSSOP-20 package | Required where field firmware updates or background data logging are needed | Select R5F10268ASP#V5 when self-programming or background data writes are mandatory |
| R5F10369ASP#V5 | Same RL78/G12 core, 4 KB code flash, 256 B RAM, identical peripheral set and pinout | Suitable for simpler control tasks with smaller firmware footprint and lower memory cost | Choose R5F10369ASP#V5 for cost-optimized designs where 4 KB flash suffices |

FAQ
What is the maximum operating frequency of the R5F10368ASP#V5?
The R5F10368ASP#V5 supports a maximum system clock frequency of 24 MHz using its factory-trimmed high-speed on-chip oscillator. When using an external crystal (X1/X2), the maximum frequency is 20 MHz at VDD ≥ 2.7 V or 16 MHz at VDD ≥ 2.4 V. Instruction execution time is 0.04167 µs at 24 MHz, enabling 31 DMIPS performance. The R5F10368ASP#V5 does not support PLL multiplication beyond these base frequencies.
Does the R5F10368ASP#V5 include data flash memory?
No, the R5F10368ASP#V5 does not include data flash memory. As confirmed in the RL78/G12 datasheet section 1.3.1, R5F103 products (including R5F10368ASP#V5) have no mounted data flash, unlike R5F102 variants which integrate 2 KB. Firmware must use code flash for non-volatile parameter storage, with appropriate wear-leveling and erase-block management implemented in software for R5F10368ASP#V5.
What serial interfaces are available on the R5F10368ASP#V5?
The R5F10368ASP#V5 provides one UART channel (UART0), one simplified SPI channel (CSI00), and one I²C-compatible interface (IICA0). It does not include CSI01, IIC01, UART1, or UART2 - all of which are exclusive to higher-pin-count or R5F102-series variants. These three interfaces share pins P10–P12 and P60–P61, with remapping possible via the Peripheral I/O Redirection Register (PIOR) for board layout flexibility in R5F10368ASP#V5 designs.
What is the operating temperature range for the R5F10368ASP#V5?
The R5F10368ASP#V5 is rated for an operating ambient temperature range of –40°C to +85°C, corresponding to the "A" (consumer) and "D" (industrial) grade variants per the part number coding. It is not qualified for the extended +105°C range denoted by "G" grade. This specification is validated under standard electrical test conditions and applies to all functional blocks including flash, RAM, ADC, and timers within the R5F10368ASP#V5 device.
How many analog input channels does the R5F10368ASP#V5 support?
The R5F10368ASP#V5 supports 8 analog input channels: ANI0 through ANI3 and ANI16 through ANI22, as specified for 20-pin R5F103x products in the RL78/G12 datasheet Table 1-1 and section 1.7. These channels connect to the 10-bit successive-approximation ADC with internal 1.45 V reference and integrated temperature sensor. Channels ANI0 and ANI1 also serve as AVREFP and AVREFM for differential reference configuration in R5F10368ASP#V5 applications.
