Renesas R5F11MPGAFB#30

Overview

R5F11MPGAFB#30 from Renesas is a 100-pin RL78/L1A 16-bit microcontroller with integrated LCD controller/driver (45 segment/8 common), 12-bit A/D and D/A converters (14/2 channels), three operational amplifiers, internal voltage reference (1.5–2.5 V), and true low-power operation (0.68 μA in Halt mode). It targets battery-powered LCD-based consumer devices such as smart meters, thermostats, and portable medical displays.

For engineers reviewing the R5F11MPGAFB#30 datasheet, R5F11MPGAFB#30 pinout, R5F11MPGAFB#30 application, or R5F11MPGAFB#30 equivalent, key selection criteria include its 128 KB flash + 8 KB data flash memory, 5.5 KB RAM, 100-pin LFQFP package, -40 to +85°C temperature grade, and integrated analog peripherals enabling single-chip LCD instrumentation.

Technical Context

The R5F11MPGAFB#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 or 30.5 μs at 32.768 kHz subsystem clock). It supports multiple clock sources: external crystal (1–20 MHz X1, 32.768 kHz XT1), high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy), and low-speed on-chip oscillator (15 kHz).

Its analog subsystem includes a 12-bit A/D converter with 14 input channels (including internal ½ AVDD), a 12-bit D/A converter with two rail-to-rail outputs (0.35 V to AVDD – 0.47 V), and three op-amps - two with analog MUX (4-input/channel) and one general-purpose - all supported by programmable internal voltage reference (1.5/1.8/2.048/2.5 V) usable for both A/D and D/A conversion.

FAQ

What is the maximum operating frequency of the R5F11MPGAFB#30, and how is it achieved?

The R5F11MPGAFB#30 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator (HOCO) in HS mode at VDD = 2.7–3.6 V. This frequency is factory-trimmed to ±1.0% accuracy across -20 to +85°C. External crystal (X1) operation supports up to 20 MHz, and the subsystem clock (XT1) runs at 32.768 kHz for RTC2. The R5F11MPGAFB#30's CISC core executes instructions in as little as 0.04167 μs at 24 MHz.

Does the R5F11MPGAFB#30 support true 12-bit D/A conversion with rail-to-rail output?

Yes, the R5F11MPGAFB#30 integrates two independent 12-bit D/A converters with rail-to-rail output capability. Each channel delivers an analog output voltage ranging from 0.35 V to AVDD – 0.47 V, supporting precise calibration and sensor excitation. These D/A outputs are fully compatible with the device's internal voltage reference (1.5/1.8/2.048/2.5 V) and operate across the full 1.8–3.6 V supply range. The R5F11MPGAFB#30 datasheet confirms this specification on page 2.

How many LCD segments and commons does the R5F11MPGAFB#30 support, and what drive methods are available?

The R5F11MPGAFB#30 supports up to 45 segment outputs and 8 common outputs, configurable for multiplexed LCD glass. It offers three drive methods: internal voltage boosting (for higher contrast), capacitor split (for low-power static/multiplexed displays), and external resistance division (for legacy compatibility). All methods are software-selectable and require no external bias ICs. This capability is confirmed in the R5F11MPGAFB#30 datasheet section 1.1 and block diagram on page 8.

What analog peripherals are integrated into the R5F11MPGAFB#30 beyond A/D and D/A converters?

Beyond its 12-bit A/D (14 channels) and 12-bit D/A (2 channels), the R5F11MPGAFB#30 integrates three operational amplifiers: one general-purpose and two with 4-input analog MUX per channel, plus a single comparator with selectable internal/external reference. It also includes an internal voltage reference generator (1.5/1.8/2.048/2.5 V) usable for both A/D and D/A, and dedicated analog supply pins (AVDD/AVSS) with separate REGC stabilization. These features are detailed in the R5F11MPGAFB#30 datasheet sections 1.1 and 1.5.2.

Is the R5F11MPGAFB#30 pin-compatible with other RL78/L1A 100-pin variants like R5F11MPFAFB#30?

Yes, the R5F11MPGAFB#30 is fully pin-compatible with other RL78/L1A 100-pin variants including R5F11MPFAFB#30 and R5F11MPEAFB#30. All share the identical PLQP0100KB-B package, 100-pin LFQFP footprint, and functionally mapped pin assignments. Differences are limited to flash capacity (128 KB vs. 96 KB vs. 64 KB) and A/D channel count (14 vs. 14 vs. 10), with no impact on PCB layout or interconnect. This compatibility is documented in Renesas' ordering information table (page 3) and pin configuration diagrams (pages 4–5).
