Product details
Overview
R5F1027AANA#65 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G12 microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It integrates 16 KB code flash, 2 KB data flash, 1.5 KB RAM, a 24 MHz high-accuracy on-chip oscillator (±1.0% over –20°C to +85°C), and supports 11-channel 10-bit A/D conversion with internal reference and temperature sensor.
For engineers reviewing the R5F1027AANA#65 datasheet, R5F1027AANA#65 pinout, R5F1027AANA#65 application, or R5F1027AANA#65 equivalent, key selection considerations include its dual-channel CSI/I²C serial interfaces, 2-channel DMA, CRC hardware acceleration, and support for SNOOZE/HALT/STOP low-power modes - all within a 4 × 4 mm, 0.5-mm pitch package suitable for space-constrained battery-powered devices.
Technical Context
The R5F1027AANA#65 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, delivering 31 DMIPS at 24 MHz while maintaining true low-power operation (63 μA/MHz). Its memory subsystem includes 16 KB code flash with 1 KB block erase granularity, 2 KB data flash supporting background operation (BGO) and 1M write cycles, and 1.5 KB SRAM with RAM guard protection.
Peripheral integration centers on mixed-signal control: an 11-channel 10-bit A/D converter with AVREFP/AVREFM inputs and on-chip temperature sensor; four 16-bit TAU timer channels with PWM capability; UART0, two CSI channels (CSI00/CSI01), two simplified I²C channels (IIC00/IIC01), and IICA0 for standard I²C bus communication - all configurable via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F1027AANA#65?
The R5F1027AANA#65 features a high-speed on-chip oscillator selectable from 1 MHz to 24 MHz, with ±1.0% accuracy over –20°C to +85°C ambient and VDD = 1.8–5.5 V. This eliminates the need for external crystals in many timing-critical applications while maintaining sufficient stability for UART baud rate generation and PWM frequency control.
Does R5F1027AANA#65 support background data flash rewriting while executing code from main flash?
Yes, R5F1027AANA#65 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - enabling seamless firmware parameter updates or logging without interrupting real-time control tasks.
How many analog input channels and what A/D resolution does R5F1027AANA#65 provide?
R5F1027AANA#65 integrates an 11-channel, 10-bit successive-approximation A/D converter with selectable internal reference (1.45 V) and on-chip temperature sensor. Input channels include ANI0–ANI3, ANI16–ANI22, supporting ratiometric measurements when paired with AVREFP/AVREFM pins.
What low-power modes are available on R5F1027AANA#65 and their typical current consumption?
R5F1027AANA#65 supports HALT (63 μA/MHz), STOP (0.52 μA typical), and SNOOZE modes. In STOP mode with RTC and LVD enabled, it draws just 0.52 μA - ideal for long-duration battery operation. Wake-up sources include key interrupts, timer events, and serial receive activity, with sub-microsecond latency from HALT.
Is R5F1027AANA#65 pin-compatible with other RL78/G12 24-pin variants like R5F10279ANA#65 or R5F10278ANA#65?
Yes, R5F1027AANA#65 shares identical pinout, package (HWQFN-24), and peripheral mapping with R5F10279ANA#65 and R5F10278ANA#65. Differences are limited to internal memory configuration (16 KB vs. 12 KB vs. 8 KB code flash) and RAM size - enabling drop-in replacement for firmware optimization or cost reduction without PCB changes.
