Renesas R7F101GAE2DSP#AA1

Overview

R7F101GAE2DSP#AA1 from Renesas is a 30-pin LSSOP-packaged RL78/G24 16-bit microcontroller featuring 64 KB code flash, 4 KB data flash, and 12 KB RAM, operating at up to 48 MHz with 50 µA/MHz active current. It integrates FAA for motor control acceleration, dual 12-bit ADCs with simultaneous sampling, DALI-2 interface, and 16-bit timers KB30–KB32 for PFC and multi-phase power conversion in lighting and digital power supplies.

For engineers reviewing the R7F101GAE2DSP#AA1 datasheet, R7F101GAE2DSP#AA1 pinout, R7F101GAE2DSP#AA1 application, or R7F101GAE2DSP#AA1 equivalent, key selection criteria include its 30-pin LSSOP package, –40°C to +85°C consumer-grade temperature range, integrated DALI-2 transceiver, and hardware-accelerated PWM timing with 651-ps average resolution in dithered mode.

Technical Context

The RL78/G24 core combines CISC architecture with a 3-stage pipeline and configurable instruction timing (0.02083 µs min at 48 MHz or 30.5 µs at 32.768 kHz), enabling dynamic trade-offs between performance and ultra-low-power operation. Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed arithmetic and limit operations, sharing 32-byte memory with the CPU for real-time motor control loop coordination.

Peripheral integration includes two independent 12-bit ADCs with dual sample-and-hold for simultaneous voltage/current sensing, four comparator channels with selectable D/A or external reference, and three 16-bit complementary-output timers (KB30–KB32) supporting interleaved PFC, forced output stop, and dithering-enabling precise gate drive timing in digitally controlled LED drivers and SMPS.

FAQ

What is the maximum operating frequency of the R7F101GAE2DSP#AA1?

The R7F101GAE2DSP#AA1 supports a maximum CPU operating frequency of 48 MHz using the on-chip PLL or high-speed oscillator. This is confirmed in the RL78/G24 datasheet (R01DS0432EJ0120 Rev.1.20, Section 1.1), where 48 MHz operation achieves a minimum instruction execution time of 0.02083 µs. The device also supports ultra-low-speed modes down to 32.768 kHz for extended battery life.

Does the R7F101GAE2DSP#AA1 include a built-in DALI-2 transceiver?

Yes, the R7F101GAE2DSP#AA1 integrates a fully compliant DALI-2 physical layer, including dedicated DALITxD0 and DALIRxD0 functions on pins P00 and P01. As specified in the datasheet (Section 1.1, "Serial interfaces"), this eliminates the need for external transceivers and ensures timing compliance with IEC 62386-102:2014 for 1200-baud half-duplex communication.

How many analog-to-digital converter channels does the R7F101GAE2DSP#AA1 support?

The R7F101GAE2DSP#AA1 supports up to 23 analog input channels with 12-bit resolution. Critically, two of these channels (ANI0–ANI3) are connected to separate sample-and-hold circuits, enabling true simultaneous sampling - a capability documented in Section 1.1 ("A/D converter") of the datasheet for accurate multi-signal acquisition in power stage monitoring.

What are the key low-power modes supported by the R7F101GAE2DSP#AA1?

The R7F101GAE2DSP#AA1 supports HALT mode (0.52 µA typical), STOP mode (0.32 µA typical), and SNOOZE mode - all detailed in Section 1.1 ("Ultra-low power consumption technology"). STOP mode retains RAM and register contents while disabling the CPU and most peripherals; wakeup occurs in under 6 µs via external interrupt or RTC alarm, making it ideal for motion-triggered lighting control.

Is the R7F101GAE2DSP#AA1 pin-compatible with other RL78/G24 variants in the same package?

Yes, the R7F101GAE2DSP#AA1 is pin-compatible with other 30-pin LSSOP RL78/G24 devices such as R7F101GAG2DSP#AA1 and R7F101G6E2DSP, as confirmed by identical pin configurations in Table 1-5 of the datasheet. All share the same 30-pin LSSOP footprint, power/ground placement, and primary peripheral mappings (e.g., DALI on P00/P01, ADC on P20–P23), enabling drop-in flash-capacity upgrades.
