Renesas R5F1057AANA#60

Overview

R5F1057AANA#60 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G11 microcontroller designed for ultra-low-power general-purpose embedded control. It integrates 16 KB code flash, 2 KB data flash, 1.5 KB RAM, 11-channel 10-bit ADC, dual comparators, 2-channel 8-bit DAC, and supports 24 MHz operation with 33 DMIPS performance at 58.3 μA/MHz active current - ideal for battery-powered sensor nodes and smart home peripherals.

For engineers reviewing the R5F1057AANA#60 datasheet, R5F1057AANA#60 pinout, R5F1057AANA#60 application, or R5F1057AANA#60 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) package, -40 to +85°C consumer-grade temperature range, integrated event link controller (ELC), data transfer controller (DTC), and support for simultaneous CSI/SPI/I²C/UART interfaces in space-constrained designs.

Technical Context

The R5F1057AANA#60 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 μs @ 24 MHz high-speed on-chip oscillator). It features four 16-bit timer array unit (TAU) channels, one 12-bit interval timer, two 8-bit interval timers, and a watchdog timer - enabling precise timing control for motor sequencing and PWM generation.

Its peripheral set includes four CSI channels, two UARTs, four simplified I²C interfaces, two multimaster I²C channels, and an event link controller supporting 18 event signal types linked to peripherals - allowing deterministic low-latency response without CPU intervention in real-time industrial monitoring applications.

FAQ

What is the operating temperature range for the R5F1057AANA#60?

The R5F1057AANA#60 is rated for consumer applications with an operating ambient temperature range of -40 to +85°C. It does not support the extended -40 to +105°C industrial grade (denoted by 'G' suffix), and thermal derating is not specified beyond this range. The device's low-power architecture ensures stable operation across this full range without external cooling.

Does the R5F1057AANA#60 support in-circuit debugging?

Yes, the R5F1057AANA#60 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the TOOL0 pin (P40) and requires no external JTAG header. However, Renesas explicitly cautions against using this function in mass-produced units due to potential flash memory rewrite limit exhaustion affecting long-term reliability.

How many analog input channels does the R5F1057AANA#60 support?

The R5F1057AANA#60 supports 11 analog input channels: ANI0 through ANI3 (on P20–P23), plus ANI16 through ANI22 (on P00, P01, P33, P32, P31, P30, and P56). All channels are accessible via the 10-bit A/D converter with internal 1.45 V reference and temperature sensor - confirmed in the RL78/G11 datasheet Section 1.5.4 and Table 1-1.

What is the maximum clock frequency supported by the R5F1057AANA#60?

The R5F1057AANA#60 supports a maximum system clock frequency of 24 MHz using the high-speed on-chip oscillator (fIH), with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = -20 to +85°C. External crystal operation is limited to 20 MHz (VDD ≥ 2.7 V), 16 MHz (VDD ≥ 2.4 V), 8 MHz (VDD ≥ 1.8 V), or 4 MHz (VDD ≥ 1.6 V) per datasheet Section 1.6.

Can the R5F1057AANA#60 perform flash memory rewrites during program execution?

Yes, the R5F1057AANA#60 supports background operation (BGO) for data flash memory rewriting: instructions can execute from program memory while data flash is being rewritten. The data flash capacity is 2 KB with 1,000,000 write cycles (typical), and voltage requirements for rewriting are VDD = 1.8–5.5 V - enabling safe firmware updates and parameter storage without halting application logic.
