Detailed Description

16-bit RL78 microcontroller with 64KB on-chip Flash, 6KB RAM, 2KB data Flash (EEPROM-like), integrated LCD controller, low-voltage detector, power-on reset, PWM, watchdog, and rich serial interfaces. Runs up to 24 MHz with an internal oscillator. Features both standard 10-bit ADC channels and high-precision 24-bit sigma-delta ADCs for accurate measurement. Wide supply range from 1.7V to 5.5V. Packaged in an 80-pin LQFP (12 x 12 mm). Designed for low-power, measurement-centric embedded applications.

Key Features

Core and speed: RL78 16-bit CPU, up to 24 MHz

Memory: 64KB Flash program memory (64K x 8), 6KB RAM, 2KB data Flash for EEPROM functions

Peripherals: LCD controller, LVD, POR, PWM, WDT

Converters: 4-channel 10-bit SAR ADC and 3-channel 24-bit sigma-delta ADC for precision sensing

Interfaces: CSI (synchronous serial), I2C, IrDA, LINbus, UART/USART

I/O: 44 general-purpose I/O pins

Power: 1.7V to 5.5V supply range

Oscillator: Internal clock source (external clock options supported per datasheet)

Package: 80-LQFP (12 x 12 mm) for surface mount

Compliance: RoHS3 compliant

Key Advantages

High accuracy measurements with integrated 24-bit sigma-delta ADCs reduce external AFE needs and BOM cost

Wide voltage range supports battery-powered and 5V industrial systems without level shifting

LCD controller built in for direct drive of segment displays, saving external drivers

Low-power RL78 architecture enables long battery life and reduced thermal load

Multiple serial interfaces (LIN, UART, I2C, CSI, IrDA) simplify connectivity to sensors, buses, and legacy systems

Robust safety features (WDT, LVD, POR) improve reliability in harsh environments

Proven Renesas ecosystem with tools, libraries, and long-term supply support

Packaging

Type: LQFP (Low-Profile Quad Flat Package), 80 pins

Material: Epoxy molding compound body, copper leadframe with lead-free tin plating (RoHS3 compliant)

Size: 12 x 12 mm body, low-profile thickness (typical LQFP form factor)

Pin pitch and lead style: Fine-pitch gull-wing leads, typical LQFP pitch 0.5 mm (refer to datasheet for exact)

Pin configuration: 80 total pins; 44 configurable GPIO; dedicated pins for VDD/VSS, ADC inputs, LCD segments/commons, serial interfaces (UART/USART, LIN, I2C, CSI), oscillator pins

Mounting: Surface mount; suitable for automated SMT assembly and reflow

Thermal characteristics: Operating ambient -40°C to +85°C (Ta); actual thermal resistance depends on PCB stack-up and airflow (see datasheet for thermal guidelines)

Electrical properties: 1.7V–5.5V supply, 24 MHz max frequency, integrated LVD/POR; ESD-protected I/Os per device spec

Supplier device package: 80-LQFP (12 x 12)

Manufacturer package/case: 80-LQFP (12 x 12)

Shipment packaging: Tray for safe handling in production

Lifecycle

Status: Active and supported by Renesas; not nearing discontinuation based on current public information

Direct equivalents and alternatives: Selection depends on required ADC precision, LCD needs, pin count, and voltage range. Drop-in, pin-compatible options typically exist within the RL78/I1C family with different Flash sizes and pin counts. Precision-measurement alternatives in Renesas portfolio include:

- RL78/I1C family variants (different memory sizes and packages for similar measurement features)

- RX23E-A series (integrated high-precision analog front end and 24-bit delta-sigma ADC for industrial sensing)

- RL78 general-purpose families (e.g., RL78/G13, RL78/G14) for applications that do not require 24-bit sigma-delta ADC

- RX and RA families for higher performance, broader peripherals, or extended temperature ranges
