Renesas R5F11EFAAFP#30

Overview

R5F11EFAAFP#30 from Renesas is a 44-pin LQFP 16 KB flash RL78/G1G 8-bit MCU with ultra-low power consumption (HALT/STOP/SNOOZE modes), 1.5 KB RAM, 12-channel 10-bit ADC, dual comparators, PGA, and integrated UART0/UART1, simplified SPI (CSI), and simplified I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.

For engineers reviewing the R5F11EFAAFP#30 datasheet, R5F11EFAAFP#30 pinout, R5F11EFAAFP#30 application, or R5F11EFAAFP#30 equivalent, key selection criteria include its 44-pin LQFP package, 16 KB code flash with self-programming, 12-channel analog input capability, ELC-triggered peripheral linking, and -40°C to +85°C operation for embedded control designs requiring mixed-signal integration and low-power runtime.

Technical Context

The R5F11EFAAFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 µs at 24 MHz high-speed on-chip oscillator). It supports multiply/divide/MAC instructions and 1 MB address space across four register banks.

Its system clocking includes dual oscillator sources: high-speed on-chip oscillator (1–24 MHz, ±2% accuracy) and external crystal/ceramic (1–20 MHz via X1/X2), with low-speed on-chip oscillator (15 kHz) for watchdog and interval timing. Power management integrates POR, LVD (6-level selectable reset/interrupt), and REGC-regulated voltage regulator.

FAQ

What is the maximum operating frequency of the R5F11EFAAFP#30 using its internal oscillator?

The R5F11EFAAFP#30 supports a maximum high-speed on-chip oscillator frequency of 24 MHz (±2% accuracy), enabling minimum instruction execution time of 0.04167 µs. This frequency is selectable via option byte and HOCODIV register settings and operates across the full VDD range (2.7–5.5 V) and temperature range (–40°C to +85°C).

Does the R5F11EFAAFP#30 support hardware debugging during production deployment?

No - the R5F11EFAAFP#30's on-chip debug function is intended solely for development and evaluation. Renesas explicitly warns against using it in mass-produced products due to potential flash memory wear-out beyond guaranteed rewrite cycles, which may compromise long-term reliability. Production units should disable or omit debug interface usage per Renesas guidance in R01DS0241EJ0150.

How many analog input channels does the R5F11EFAAFP#30 provide, and what is their resolution?

The R5F11EFAAFP#30 provides 12 analog input channels with 10-bit resolution (configurable to 8-bit). Channels include ANI0–ANI7 on Port 2, plus ANI16–ANI19 on Ports 0, 12, and 14. The ADC uses VDD as reference and supports internal 1.45 V reference and temperature sensor readout - all operable within the 2.7–5.5 V supply range.

Can the R5F11EFAAFP#30 drive standard 5 V logic inputs while operating at 3.3 V VDD?

Yes - selected pins (P01, P10, P15–P17, P30, P31, P50) include TTL-compatible input buffers, accepting VIH ≥ 2.0 V (at VDD = 3.3 V) and VIL ≤ 0.5 V. This allows direct interfacing with 5 V logic outputs without level shifters, provided VDD remains ≥ 2.7 V and absolute maximum ratings (VI ≤ VDD + 0.3 V) are observed.

What packaging and ordering options are available for the R5F11EFAAFP#30?

The R5F11EFAAFP#30 is supplied in 44-pin plastic LQFP (10 × 10 mm, 0.80-mm pitch) in tray packaging (#10, #30, #70 suffixes). The "FP" in the part number denotes LQFP; "#30" specifies tray packaging. No tape-and-reel or pre-programmed variants are indicated for this specific ordering code in the RL78/G1G datasheet.
