Product details
Overview
R5F1057AANA#00 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 delivering 33 DMIPS - deployed in battery-powered sensor nodes, smart home controllers, and industrial I/O modules.
For engineers reviewing the R5F1057AANA#00 datasheet, R5F1057AANA#00 pinout, R5F1057AANA#00 application, or R5F1057AANA#00 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) footprint, 1.6–5.5 V supply range, STOP/HALT/SNOOZE low-power modes, and integrated event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R5F1057AANA#00 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 μs (24 MHz high-speed on-chip oscillator) to 66.6 μs (15 kHz low-speed oscillator). Its clock system includes selectable high-speed (up to 24 MHz ±1.0%), middle-speed (4/2/1 MHz), and low-speed (15 kHz) on-chip oscillators, plus external crystal support (1–20 MHz).
Peripheral integration centers on deterministic real-time response: the Event Link Controller (ELC) routes 18 event signals directly to peripherals (e.g., ADC start on timer match), while the Data Transfer Controller (DTC) handles up to 24 activation sources across normal, repeat, and block transfer modes - enabling zero-CPU-overhead data movement between ADC, UART, and memory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1057AGNA#U0 | Same silicon, industrial-grade (-40°C to +105°C) temperature rating; identical pinout and electrical specs | Suitable for under-hood automotive or factory-floor equipment where extended temperature range is required | Select when operating ambient exceeds +85°C; no design changes needed beyond qualification testing |
| R5F1056AASM#10 | 20-pin TSSOP package; 10-channel ADC; reduced I/O count (17 pins vs. 21); same core/peripherals otherwise | Better suited for space-constrained PCBs with fewer analog/sensor interfaces and no need for 24-pin routing density | Choose for cost-sensitive, lower-complexity designs where 20-pin TSSOP simplifies assembly and reduces board area |
Compared with R5F1057AGNA#U0, the R5F1057AANA#00 trades extended temperature range for consumer-grade qualification and tube packaging; versus R5F1056AASM#10, it adds three ADC channels, four I/O pins, and HWQFN thermal performance - justifying use in higher-fidelity sensing applications.

FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F1057AANA#00?
The R5F1057AANA#00 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS (Dhrystone MIPS) performance. This benchmark reflects real-world integer computation throughput for control algorithms, and the 24 MHz clock is factory-trimmed to ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C - eliminating need for external crystal in many timing-tolerant applications.
Does the R5F1057AANA#00 support in-system programming and secure firmware updates?
Yes, the R5F1057AANA#00 supports full in-system programming via its on-chip debug interface and UART-based bootloader. It includes boot swap functionality for atomic firmware updates and a flash shield window to prevent unauthorized access to protected memory regions - enabling secure over-the-air (OTA) updates in field-deployed devices without requiring physical reprogramming.
How many analog input channels does the R5F1057AANA#00 provide, and what reference options are available?
The R5F1057AANA#00 provides 11 analog input channels (ANI0–ANI3, ANI16–ANI22) with 10-bit resolution. Reference options include external AVREFP/AVREFM pins, internal 1.45 V bandgap reference, and VDD - allowing flexible sensor interfacing across varying supply voltages and precision requirements without external reference ICs.
What low-power modes are available on the R5F1057AANA#00, and what is the lowest achievable current consumption?
The R5F1057AANA#00 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the low-voltage detector (LVD) active, it achieves 0.64 μA typical current consumption at 25°C - verified across the full 1.6–5.5 V supply range. Wake-up is supported via external interrupt, comparator output, or RTC alarm, making it ideal for long-life battery applications.
Is the R5F1057AANA#00 pin-compatible with other RL78/G11 variants such as the R5F1056A or R5F1058A?
No, the R5F1057AANA#00 is not pin-compatible with R5F1056A (20-pin) or R5F1058A (25-pin WFLGA). It uses a 24-pin HWQFN package with unique pin mapping - including dedicated KR5–KR7 key return inputs and expanded CSI/I²C channel assignments. Migration requires PCB layout revision and I/O remapping in firmware due to differing pin counts and function allocations.
