Renesas R5F11MPEAFB#30

Overview

R5F11MPEAFB#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), rail-to-rail operational amplifiers (3 channels, 2 with analog MUX), internal voltage reference (1.5–2.5 V), and real-time clock 2 with calendar function. It operates from 1.8 V to 3.6 V, delivers 33 DMIPS at 24 MHz, and targets ultra-low-power LCD-based consumer instrumentation.

For engineers reviewing the R5F11MPEAFB#30 datasheet, R5F11MPEAFB#30 pinout, R5F11MPEAFB#30 application, or R5F11MPEAFB#30 equivalent, key selection criteria include its 100-pin LFQFP package, 64 KB flash + 8 KB data flash + 5.5 KB RAM memory configuration, HALT-mode current of 0.68 μA (RTC2 + LVD enabled), and support for capacitor-split/internal-boost LCD drive methods.

Technical Context

The R5F11MPEAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz HOCO or 30.5 μs @ 32.768 kHz subsystem clock). It integrates an Event Link Controller (22 event inputs) and Data Transfer Controller (30 activation sources) for autonomous peripheral coordination without CPU intervention.

Its analog subsystem includes three operational amplifiers (AMP0–AMP2), one comparator, and dual 12-bit converters sharing AVDD/AVSS rails and internal reference voltage (1.45 V TYP.). The LCD controller supports programmable bias generation via internal boosting, capacitor split, or external resistor division - configurable per application requirements.

FAQ

What is the maximum LCD segment count supported by the R5F11MPEAFB#30?

The R5F11MPEAFB#30 supports up to 45 segment outputs and 8 common outputs, enabling multiplexed LCD configurations up to 45 × 8 = 360 segments. This is confirmed in the RL78/L1A datasheet Section 1.6, which specifies "45 (41)" segment signals for 100-pin products. The R5F11MPEAFB#30 uses the full 100-pin variant and thus achieves the higher segment count.

Does the R5F11MPEAFB#30 include an internal voltage reference for its ADC and DAC?

Yes, the R5F11MPEAFB#30 includes an internal voltage reference that can be selected as 1.5 V, 1.8 V, 2.048 V, or 2.5 V (typical values), and it is explicitly usable as the reference source for both the 12-bit A/D and D/A converters. This is documented in Section 1.1 "Features" and Section 1.6 "Outline of Functions" of the R01DS0280EJ0130 datasheet.

What are the power consumption characteristics of the R5F11MPEAFB#30 in low-power modes?

The R5F11MPEAFB#30 achieves 0.68 μA in HALT mode with RTC2 and LVD enabled, and 70.8 μA/MHz in active mode at 24 MHz. These values are specified in the datasheet's "Features" section and verified under TA = −40 to +85°C and VDD = 1.8–3.6 V. The low HALT current enables multi-year battery operation in portable LCD instruments.

How many operational amplifiers does the R5F11MPEAFB#30 integrate, and what are their key capabilities?

The R5F11MPEAFB#30 integrates three operational amplifiers: one general-purpose (AMP0) and two rail-to-rail types (AMP1 and AMP2), with AMP1 and AMP2 each supporting a 4-input analog multiplexer (MUX10–MUX13 and MUX00–MUX03). This configuration allows flexible sensor signal routing and conditioning - critical for multi-channel analog front-ends in medical and industrial devices.

Is the R5F11MPEAFB#30 pin-compatible with other RL78/L1A family members?

The R5F11MPEAFB#30 shares the same 100-pin LFQFP package and pinout with R5F11MPFAFB#30 and R5F11MPGAFB#30, making them pin-compatible within the 100-pin subgroup. However, it is not pin-compatible with 80-pin variants like R5F11MMFAFB#30 due to differing pin counts and I/O allocations - confirmed in Table 1-1 and Section 1.3.2 of the datasheet.
