Product details
Overview
R7F100GLJ2DFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 48-KB RAM RL78/G23 16-bit microcontroller operating at 1.6–5.5 V, featuring ultra-low-power operation (41 µA/MHz), 210-nA data retention, integrated capacitive touch sensing (CTSU2L), and dual 16-bit timer arrays for industrial control and sensor interface applications.
For engineers reviewing the R7F100GLJ2DFB#AA0 datasheet, R7F100GLJ2DFB#AA0 pinout, R7F100GLJ2DFB#AA0 application, or R7F100GLJ2DFB#AA0 equivalent, key selection considerations include its 64-pin LFQFP-0.5 mm package, -40°C to +85°C consumer-grade temperature range, 512-KB code flash with 8-KB data flash, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The R7F100GLJ2DFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz or 30.5 µs @ 32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 low-power autonomous processes using 21 command types, enabling intermittent operation without CPU, flash, or RAM activation.
Its peripheral set includes a Logic and Event Link Controller (ELCL) for hardware-level signal routing between peripherals, a 10-channel I²C/Simplified I²C interface, six UART/UARTA channels (LIN-capable), and a 26-channel 12-bit A/D converter with internal 1.48-V reference and on-die temperature sensor - all operating within the same 1.6–5.5 V supply range.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLJ2DFB#AA0?
The R7F100GLJ2DFB#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation down to 32.768 kHz for RTC and deep-sleep functions, maintaining full functionality across the entire voltage range.
Does the R7F100GLJ2DFB#AA0 support in-system programming and secure firmware updates?
Yes, the R7F100GLJ2DFB#AA0 supports full in-system programming via on-chip debugging interface and includes flash shield window protection. It enables secure firmware updates through self-programming with boot swapping - allowing validated new firmware to be written to a secondary bank while the system runs from the primary bank, then atomically switching execution upon successful verification.
How many capacitive touch channels does the R7F100GLJ2DFB#AA0 support, and what configurations are available?
The R7F100GLJ2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual-capacitance matrix mode (8 × 8 pin configuration). It operates over the full 1.8–5.5 V supply range and includes built-in noise cancellation, auto-calibration, and drift compensation - all implemented in hardware without CPU involvement.
What communication interfaces are available on the R7F100GLJ2DFB#AA0, and how many instances of each are supported?
The R7F100GLJ2DFB#AA0 provides up to 10 I²C/Simplified I²C channels, 6 UART/UARTA channels (with LIN-bus protocol support), and 8 simplified SPI (CSI) channels. All interfaces are implemented in the Serial Array Unit (SAU) and can be flexibly assigned to multiple pin groups via the Peripheral I/O Redirection Register (PIOR), enabling simultaneous use of multiple protocols without resource conflict.
Is the R7F100GLJ2DFB#AA0 pin-compatible with other RL78/G23 variants such as R7F100GLL2DFB#AA0 or R7F100GMJ2DFB#AA0?
No, the R7F100GLJ2DFB#AA0 is not pin-compatible with R7F100GLL2DFB#AA0 (same 64-pin LFQFP package but different temperature grade) or R7F100GMJ2DFB#AA0 (80-pin LFQFP package). While R7F100GLJ2DFB#AA0 and R7F100GLL2DFB#AA0 share identical pinout, electrical characteristics, and functionality, R7F100GMJ2DFB#AA0 has 16 additional pins and distinct pin mapping - requiring PCB redesign for migration.
