Product details
Overview
UPD78F1503AGC-UEU-M1-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/LG3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated 10-bit ADC with 24 channels. It operates at up to 20 MHz, supports 5 V operation, and includes UART, CSI, I²C, and timer peripherals. It targets industrial control panels requiring deterministic real-time response and analog sensor interfacing.
For engineers reviewing the UPD78F1503AGC-UEU-M1-AX datasheet, UPD78F1503AGC-UEU-M1-AX pinout, UPD78F1503AGC-UEU-M1-AX application, or UPD78F1503AGC-UEU-M1-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with RA78K0R toolchain and QB-MINI2 debugger.
Technical Context
The UPD78F1503AGC-UEU-M1-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture. It integrates a 3-channel 16-bit timer array unit (TAU), watchdog timer, and voltage monitor with reset generation.
Its peripheral set includes a 10-bit successive-approximation ADC with sample-and-hold, 2-channel UART with LIN support, 2-channel CSI for synchronous serial communication, and I²C-compatible interface supporting master/slave modes - all directly memory-mapped and controllable via SFRs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10PLGCLFB#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower max clock (24 MHz), no hardware LIN support. | Better suited for cost-constrained, lower-peripheral-count applications; lacks TAU and 24-channel ADC. | Select if migrating to Renesas' newer RL78 platform with toolchain continuity and lower power, but accept reduced analog integration. |
| UPD78F1504AGC-UEU-M1-AX | Same 78K0R/LG3 family; 256 KB Flash, identical peripherals and pinout - direct upgrade path. | Enables larger firmware images (e.g., OTA stack, advanced diagnostics) without PCB change. | Choose when future firmware expansion or field-upgrade capability is required; same layout, same thermal profile. |
Compared with UPD78F1503AGC-UEU-M1-AX, R5F10PLGCLFB#30 offers modern low-power architecture but sacrifices ADC channel count and LIN hardware, while UPD78F1504AGC-UEU-M1-AX provides seamless Flash capacity scaling with zero hardware redesign effort.
