Detailed Description

16-bit RL78 microcontroller with 256 KB on-chip Flash and 20 KB RAM in an 80-pin low profile fine pitch quad flat package

Operates from 1.6 V to 5.5 V with low power consumption and on-chip oscillator

General purpose MCU for embedded control with rich analog, timing, and communication peripherals

RoHS3 compliant and suitable for industrial temperature range from minus 40 to plus 85 degrees Celsius

Key Features

RL78 core running up to 32 MHz for efficient 16-bit processing

256 KB Flash program memory and 20 KB RAM for medium to large applications

64 programmable I O pins for broad peripheral expansion

17 channel A D converter with 8 or 10 bit resolution selection

On chip peripherals including DMA, low voltage detect, power on reset, PWM timers, watchdog timer

Communication interfaces including CSI SPI, I2C, LIN bus, UART and USART

Internal oscillator for simplified clock design plus support for external clocks if needed

Wide supply range from 1.6 V to 5.5 V supporting battery or regulated supplies

RL78 G13 series ecosystem compatibility for tools, libraries, and software

Key Advantages

Very low power architecture with flexible clocking for long battery life

Broad peripheral mix reduces external components and BOM cost

Wide voltage and temperature range increases design robustness

Mature RL78 platform with extensive documentation and tooling support

80 pin footprint offers ample I O for complex designs while remaining compact

Proven reliability from Renesas for long term industrial deployments

Packaging

Type 80 LFQFP also called 80 LQFP low profile fine pitch quad flat package

Body size about 12 mm by 12 mm low profile plastic epoxy molded package with copper leadframe

Pin configuration 80 leads arranged on four sides approximately 20 pins per side with fine pitch typically 0.5 mm

Mounting Surface mount compatible with standard SMT reflow processes

Lead finish matte tin lead free and RoHS3 compliant

Thermal characteristics typical of LQFP without exposed pad heat is conducted through leads and into the PCB use generous copper and thermal vias for best results ambient operation from minus 40 to plus 85 degrees Celsius

Electrical properties support 1.6 to 5.5 V operation robust ESD protection integrated reference for ADC internal oscillator and reset circuitry

Shipment format Tape and Reel TR for automated assembly

Lifecycle

Current status Active and not nearing discontinuation based on the ongoing RL78 G13 family support

Pin compatible and close equivalents within RL78 G13 family include variants with the same 80 pin footprint and similar memory and speed options with different order suffixes for temperature grade and packaging

Functional alternatives within Renesas include RL78 G14 for additional performance and peripherals and RA2 series microcontrollers such as RA2E1 or RA2L1 for ARM based designs if you seek future migration paths and ecosystem alignment
