Renesas R5F1007AANA#20

Overview

R5F1007AANA#20 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26-channel), and real-time clock with calendar function - deployed in battery-powered sensor nodes and industrial control interfaces.

For engineers reviewing the R5F1007AANA#20 datasheet, R5F1007AANA#20 pinout, R5F1007AANA#20 application, or R5F1007AANA#20 equivalent, key selection criteria include its 24-pin HWQFN-0.5mm-pitch package, 16 KB code flash with self-programming and flash shield window, 4 KB background-operable data flash (1M rewrite cycles), and support for UART/LIN, I²C, and CSI serial interfaces in consumer-grade (-40°C to +85°C) operation.

Technical Context

The R5F1007AANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates on-chip power-on-reset, voltage detector (14-level LVD), and DMA controller with 2 channels supporting 2-clock transfers between SFR and RAM.

Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with alarm/calendar/correction, one watchdog timer, and a 10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating within the same 1.6–5.5 V supply range as the core logic.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F1007AANA#20?

The R5F1007AANA#20 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. The RL78 core's 3-stage pipeline and optimized instruction set deliver deterministic timing critical for real-time control loops in the R5F1007AANA#20.

Does the R5F1007AANA#20 include an integrated temperature sensor, and how is it accessed?

Yes, the R5F1007AANA#20 includes an on-chip temperature sensor usable only in HS (high-speed main) mode. It is accessed via dedicated ADC channel ANI21 (P27), with conversion results referenced to the internal 1.45 V bandgap voltage. Calibration data is not factory-trimmed, so system-level offset/gain compensation is required - documented in the R5F1007AANA#20 hardware manual Section 28.3.2.

Can the R5F1007AANA#20 perform flash self-programming while executing code from main memory?

Yes, the R5F1007AANA#20 supports self-programming of both code flash and data flash using the on-chip flash library. Code execution continues from main memory during reprogramming, and the flash shield window function prevents unintended writes. The R5F1007AANA#20 requires dedicated RAM sections (e.g., FF300H for #20 variant) for library operation - detailed in the Flash Self-Programming Library documentation R20UT2944.

What serial communication interfaces are available on the R5F1007AANA#20, and which pins support LIN bus functionality?

The R5F1007AANA#20 provides UART/LIN (2 channels), CSI (2–8 channels), and I²C/Simplified I²C (3–10 channels). LIN functionality is implemented on UART0 and UART1 - specifically, P11 (RxD0/TOOLRxD) and P12 (TxD0/TOOLTxD) support LIN physical layer signaling including slew-rate control and dominant timeout detection per ISO 17987. This is confirmed in the R5F1007AANA#20 electrical characteristics table.

Is the R5F1007AANA#20 qualified for industrial temperature range, or only consumer grade?

The R5F1007AANA#20 is rated for -40°C to +85°C operation, designated by the 'A' suffix in the part number per Renesas' ordering guide. It is specified for consumer applications, not industrial-grade (-40°C to +105°C, denoted by 'G') or extended industrial ('D'). Thermal derating and voltage margin validation must be performed separately if deployed outside the certified range - the R5F1007AANA#20 datasheet explicitly limits ambient temperature to +85°C maximum.
