Product details
Overview
UPD78F1848AGC-UEU-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KG3-C family, featuring 512 KB on-chip Flash memory, 32 KB RAM, and integrated peripherals including 12-bit ADC (16 channels), 32-bit timer, UART, I²C, and CAN 2.0B controller. It operates at up to 20 MHz and targets automotive body control modules requiring functional safety support.
For engineers reviewing the UPD78F1848AGC-UEU-AX datasheet, UPD78F1848AGC-UEU-AX pinout, UPD78F1848AGC-UEU-AX application, or UPD78F1848AGC-UEU-AX equivalent, key selection criteria include CAN interface compliance, Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +125°C), and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
The UPD78F1848AGC-UEU-AX implements the 78K0R CPU core with 16-bit architecture and supports real-time interrupt handling via 16 priority-level vectors. It integrates a dedicated CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames with message buffering and automatic retransmission.
On-chip power management includes low-power modes (HALT, STOP, and SNOOZE) with wake-up capability via external interrupt or peripheral event. The device uses a single 5 V supply and features internal voltage regulation for core logic, with separate analog supply pins (AVDD/AVSS) for noise isolation of the 12-bit ADC subsystem.
