R7F100T7E3G00CNP#HA0

Overview

The R7F100T7E3G00CNP#HA0 is a 16-bit microcontroller from the Renesas RL78/G23 family. It features a 32 MHz CPU core, 128 kB of program memory, and 16 kB of data RAM. The device is housed in a 40-pin HWQFN package and supports an operating temperature range of -40°C to +105°C. Key peripherals include up to 36 I/O lines, multiple communication interfaces such as I2C, SPI, and UART, and an ADC with selectable resolution of 8, 10, or 12 bits across 9 channels.

Feature Summary

• Integrated capacitive touch sensing controller supporting up to 19 channels for direct sensor interface without external components.
• High-performance 16-bit RL78 core optimized for low power consumption while maintaining processing speed up to 32 MHz.
• Comprehensive peripheral set including programmable PWM timers, watchdog timer, and low voltage detection for robust system control.

Applications

• Capacitive touch switch panels for home appliances and consumer electronics
• General-purpose control units requiring integrated touch sensing capabilities
• Battery-powered devices benefiting from the MCU's low power operation modes

Procurement Notes

Verify the specific suffix #HA0 against the official Renesas datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the HWQFN-40 package. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a single-chip solution combining general MCU functions with capacitive touch sensing is required. Compare memory sizes and I/O counts against other RL78/G23 variants to ensure sufficient resources for the application logic. Consider the 40-pin package constraint if board space is limited.

Part Context

This part belongs to the RL78/G23 series, which integrates capacitive touch controllers directly into the microcontroller architecture. This integration reduces bill-of-materials count and simplifies design compared to separate MCU and touch IC solutions within the same Renesas portfolio.

Replacement Considerations

Direct substitutes within the RL78/G23 family may exist with different memory sizes or package options. Verify functional equivalence of the integrated touch controller and peripheral sets before swapping. Consult Renesas documentation for cross-reference lists.
