Product details
Overview
R5F51308ADFK#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), and IEC60730-compliant safety functions for industrial control and appliance HMI applications.
For engineers reviewing the R5F51308ADFK#30 datasheet, R5F51308ADFK#30 pinout, R5F51308ADFK#30 application, or R5F51308ADFK#30 equivalent, key selection criteria include its LQFP-64 (PLQP0064GA-A, 14×14 mm, 0.8 mm pitch) package, –40°C to +85°C temperature grade, integrated RTC with calendar mode, low-power software standby (0.37 µA), and ELC-driven event-linked peripheral operation without CPU wake-up.
Technical Context
The R5F51308ADFK#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32-bit multiply. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for real-time frequency accuracy monitoring.
Peripheral integration includes MTU2 (6-channel 16-bit timer with complementary PWM), SCIg (3 channels), RIIC (1 channel, up to 400 kbps), RSPI (1 channel, up to 16 Mbps), REMC (2 channels, 4-pattern matching), and CTSU (32-key mutual capacitance support). All operate under ELC event triggering or DTC-initiated transfers, enabling deterministic low-power operation.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51308ADFK#30?
The R5F51308ADFK#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its architecture supports single-cycle 32×32-bit multiplication and fast interrupt response, making it suitable for real-time control tasks in appliances and industrial systems. The R5F51308ADFK#30 achieves this performance with no wait states on flash access and deterministic instruction execution.
Does the R5F51308ADFK#30 support real-time clock functionality with calendar mode?
Yes, the R5F51308ADFK#30 includes a hardware RTC module supporting both binary count and calendar count modes, with leap-year and 30-second adjustment functions. It uses the 32.768 kHz sub-clock oscillator as its time base and provides 1 Hz or 64 Hz output on the RTCOUT pin. This capability is fully implemented in the R5F51308ADFK#30 and does not require external components.
How many capacitive touch channels does the R5F51308ADFK#30 support, and what method is used?
The R5F51308ADFK#30 supports up to 32 capacitive touch sensing channels using the mutual capacitance method, enabled by its integrated CTSU peripheral. This configuration allows matrix-based key layouts with high noise immunity and supports up to 324 keys in larger-package variants-but is limited to 32 channels on the 64-pin LQFP (PLQP0064GA-A) package of the R5F51308ADFK#30.
What low-power modes and current consumption values are specified for the R5F51308ADFK#30?
The R5F51308ADFK#30 supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it consumes just 0.37 µA while maintaining RTC and LPT operation. Recovery time from this state is 4.8 µs. High-speed operating mode draws 96 µA/MHz. These values are measured and guaranteed for the R5F51308ADFK#30 under its rated voltage and temperature conditions.
Is the R5F51308ADFK#30 pin-compatible with other RX130 Group members in the same package?
Yes, the R5F51308ADFK#30 is pin-compatible with other RX130 Group MCUs in the PLQP0064GA-A (64-pin LQFP, 0.8 mm pitch) package, including R5F51307ADFK#30 and R5F51306BDFK#30. Pin functions, power domains, and peripheral mappings are consistent across these variants-enabling hardware reuse and firmware scalability within the same footprint. This compatibility applies specifically to the R5F51308ADFK#30 and its direct package-matched siblings.
