Product details
Overview
R5F5110HAGNF#20 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 8 KB on-chip flash, 8 KB SRAM, 12-bit A/D converter with 7 input channels, RTC, and dual SCI interfaces - deployed in low-power industrial sensor nodes requiring deterministic real-time control.
For engineers reviewing the R5F5110HAGNF#20 datasheet, R5F5110HAGNF#20 pinout, R5F5110HAGNF#20 application, or R5F5110HAGNF#20 equivalent, key selection criteria include its 40-pin HWQFN (PWQN0040KC-A) package, −40 to +105°C temperature grade, 1.8–3.6 V supply range, software standby current of 0.35 μA, and support for IEC 60730-compliant safety functions.
Technical Context
The R5F5110HAGNF#20 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its on-chip clock system integrates high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators, with clock frequency accuracy measurement (CAC) for self-validation.
It supports IEC 60730 compliance via integrated RAM test assist logic, IWDT, and CAC - all operating independently of main CPU execution. The DTC enables interrupt-triggered data transfers without CPU intervention, while the MTU2 timer unit provides phase counting and PWM output across four channels for motor control timing.

FAQ
What is the maximum operating frequency of the R5F5110HAGNF#20 and under what voltage conditions?
The R5F5110HAGNF#20 operates at a maximum frequency of 32 MHz, achievable only when the supply voltage (VCC) is between 2.7 V and 3.6 V. At 1.8–2.4 V, the maximum frequency is limited to 8 MHz; at 2.4–2.7 V, it is 16 MHz. This voltage-frequency scaling ensures reliable operation across its full 1.8–3.6 V range.
Does the R5F5110HAGNF#20 support IEC 60730 functional safety compliance?
Yes, the R5F5110HAGNF#20 includes on-chip features required for Class B compliance per IEC 60730: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, and RAM test assist logic. These operate autonomously and are documented in Renesas' RX110 Functional Safety Manual.
How many A/D converter input channels does the R5F5110HAGNF#20 provide, and what is their resolution?
The R5F5110HAGNF#20 integrates a single 12-bit A/D converter with 7 analog input channels (AN000–AN004, AN006). It achieves a minimum conversion time of 1.0 µs when the ADCLK runs at 32 MHz, supporting scan, group scan, and double-trigger modes for motor control synchronization.
What package type and dimensions does the R5F5110HAGNF#20 use?
The R5F5110HAGNF#20 uses the PWQN0040KC-A package: a 40-pin HWQFN measuring 6 mm × 6 mm with 0.5 mm pin pitch and an exposed thermal pad. Renesas recommends connecting the exposed pad to VSS for optimal thermal performance and noise immunity.
Which communication interfaces are available on the R5F5110HAGNF#20?
The R5F5110HAGNF#20 provides two SCI channels (SCI1 and SCI12), one I²C bus interface (RIIC), and one RSPI channel. SCI1 supports asynchronous, clock-synchronous, simple I²C, and simple SPI modes; SCI12 adds extended serial mode (RXDX12/TXDX12/SIOX12); RIIC operates up to 400 kbps; RSPI supports master/slave up to 16 Mbps.
