Product details
Overview
R5F2LA88ADFP#30 from Renesas is an 80-pin LQFP D-version 16-bit R8C/LA8A Group MCU with 64 KB program flash, 2 KB × 2 data flash, 3.5 KB RAM, 72 programmable I/O ports, and integrated LCD drive (40 segment/4 common), 12-channel 10-bit ADC, and Timer RJ0–RJ2 (16-bit × 3). It operates from 1.8 V to 5.5 V and supports −40°C to +85°C ambient temperature for use in industrial appliance control panels.
For engineers reviewing the R5F2LA88ADFP#30 datasheet, R5F2LA88ADFP#30 pinout, R5F2LA88ADFP#30 application, or R5F2LA88ADFP#30 equivalent, key selection criteria include its 80-pin LQFP package, 12-channel ADC with temperature sensor, real-time clock (Timer RH), three 16-bit Timer RJ units, and dual UART/I²C/SSU serial interfaces for embedded HMI and sensor-aggregation systems.
Technical Context
The R5F2LA88ADFP#30 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory architecture includes on-chip program ROM, dual-bank data flash for safe firmware updates, and RAM with dedicated register banks (R0H/R0L through R3).
Peripheral integration centers on system-level timing and interface control: Timer RH provides calendar-based real-time clock functions; Timer RJ0–RJ2 support pulse width measurement, event counting, and PWM generation; UART0 and UART2 (with I²C mode) enable host communication and sensor bus interfacing; and the LCD controller drives up to 40 segments without external bias circuitry.

FAQ
What is the maximum operating frequency and voltage range for the R5F2LA88ADFP#30?
The R5F2LA88ADFP#30 supports a maximum operating frequency of 20 MHz when powered at 2.7 V to 5.5 V, and 8 MHz at 1.8 V to 5.5 V. Its wide 1.8–5.5 V supply range allows direct interface with legacy 5 V logic, modern 3.3 V systems, and single-cell Li-ion or triple-AA battery configurations without level-shifting.
Does the R5F2LA88ADFP#30 include an integrated temperature sensor?
Yes, the R5F2LA88ADFP#30 integrates a calibrated on-die temperature sensor usable via the 10-bit ADC. It supports measurement across −20°C to +85°C (N version) or −40°C to +85°C (D version), with accuracy specified per Renesas datasheet R01DS0011EJ0101 - enabling thermal monitoring in appliances without external sensor components.
How many UART and I²C interfaces does the R5F2LA88ADFP#30 support?
The R5F2LA88ADFP#30 provides two independent serial channels: UART0 and UART2. UART2 supports hardware I²C-bus mode, allowing it to function as a full I²C master or slave. The device does not include a dedicated standalone I²C peripheral - I²C functionality is multiplexed onto UART2 pins and controlled via UART registers.
What LCD configuration options are supported by the R5F2LA88ADFP#30?
The R5F2LA88ADFP#30 LCD controller supports static, 1/2, 1/3, and 1/4 duty drive with 1/2 or 1/3 bias. It delivers up to 40 segment outputs and 4 common outputs, enabling direct drive of alphanumeric or custom segment displays up to 160 segments (40 × 4) without external bias circuitry or external drivers.
Is on-chip debug supported for the R5F2LA88ADFP#30, and what interface is used?
Yes, the R5F2LA88ADFP#30 supports on-chip debug via Renesas' single-wire debug (SWD) interface using the RESET pin. This eliminates the need for a dedicated debug header, reduces PCB footprint, and enables full breakpoint, watchpoint, and memory inspection capabilities during development and field firmware updates.
