Renesas R7F100GPK2DFB#AA0

Overview

R7F100GPK2DFB#AA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM. It delivers ultra-low power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA (6 channels), IICA (10 channels), and CSI (8 channels).

For engineers reviewing the R7F100GPK2DFB#AA0 datasheet, R7F100GPK2DFB#AA0 pinout, R7F100GPK2DFB#AA0 application, or R7F100GPK2DFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP package with exposed thermal pad, industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU intervention.

Technical Context

The R7F100GPK2DFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential operations using 21 command types, enabling autonomous analog sensing and signal processing while the CPU, flash, and RAM remain powered down.

Its peripheral set includes a Logic and Event Link Controller (ELCL) that routes event signals between peripherals via programmable logic gates and flip-flops, and a Data Transfer Controller (DTC) supporting normal, repeat, block, and chain transfer modes triggered by interrupt sources - eliminating CPU overhead for memory-mapped peripheral data movement.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPK2DFB#AA0?

The R7F100GPK2DFB#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains timing specifications across −40 to +105°C ambient temperature when supplied within this voltage window.

Does the R7F100GPK2DFB#AA0 support hardware encryption or secure boot features?

The R7F100GPK2DFB#AA0 does not integrate hardware AES, SHA, or secure boot engines. Its security features are limited to code flash block erase/write prohibition and flash shield window protection - sufficient for basic IP protection but not cryptographic authentication or trusted boot. For secure firmware validation, external secure elements or software-based hash verification must be implemented.

Can the R7F100GPK2DFB#AA0 drive standard 5 V logic interfaces directly?

No. The R7F100GPK2DFB#AA0 I/O pins are not 5 V tolerant. Its GPIOs operate at VDD level (1.6–5.5 V), but absolute maximum voltage is VDD + 0.3 V. To interface with 5 V systems, level-shifting circuitry (e.g., TXB0104 or discrete MOSFET translators) is required - especially for UART, I²C, and SPI lines connected to legacy 5 V peripherals.

How many independent I²C interfaces does the R7F100GPK2DFB#AA0 support, and what are their addressing capabilities?

The R7F100GPK2DFB#AA0 supports up to 10 IICA (I²C-compatible) channels, each configurable as master or slave. Each channel supports standard-mode (100 kbps) and fast-mode (400 kbps) operation, 7-bit and 10-bit slave addressing, and clock stretching. Channel 0 (P60/P61) is dedicated and fully independent; others share pins via peripheral I/O redirection (PIOR) and require careful multiplexing management.

Is the exposed thermal pad on the R7F100GPK2DFB#AA0 package electrically connected internally, and how should it be handled on the PCB?

Yes, the exposed thermal pad on the R7F100GPK2DFB#AA0's 100-pin LFQFP package is internally connected to VSS. It must be soldered to a solid VSS copper pour on the PCB with ≥4 thermal vias (0.3 mm diameter) to an inner ground plane. This connection is mandatory for thermal dissipation, electrical noise reduction, and stable operation - failure to do so risks thermal shutdown and increased EMI susceptibility.
