Product details
Overview
UPD70F4000AM1GCA-UEU-AX from Renesas Electronics is a 32-bit V850E2/FL4 single-chip microcontroller featuring 1.2 MB code flash, 128 KB RAM, dual 12-bit ADCs (up to 24 channels), 6-channel 32-bit timer units, and integrated FlexRay, CAN, UART, CSI, and I²C interfaces. It operates at up to 120 MHz with 1.2 V core supply and supports automotive-grade ambient temperature range (−40 °C to +110 °C) in a 176-pin LQFP package.
For engineers reviewing the UPD70F4000AM1GCA-UEU-AX datasheet, UPD70F4000AM1GCA-UEU-AX pinout, UPD70F4000AM1GCA-UEU-AX application, or UPD70F4000AM1GCA-UEU-AX equivalent, key selection considerations include its dual-isolated power domains (ISO0/ISO1), AWO (Always-On) regulator for low-power wake-up, FlexRay v2.1A compliance, and support for ASIL-B functional safety development per ISO 26262.
Technical Context
The UPD70F4000AM1GCA-UEU-AX implements the V850E2 CPU core with 32-bit RISC architecture, Harvard memory organization, and 5-stage pipeline. It integrates two independent voltage domains-ISO0 for analog/peripheral subsystems (ADC, comparators, FlexRay) and ISO1 for high-speed digital I/O (B0VDD-supplied ports)-enabling selective power gating and domain-specific voltage scaling.
Its clock system includes a main oscillator (1–20 MHz), sub-oscillator (32.768 kHz), internal RC oscillator (8 MHz), and PLL supporting CPU clock generation up to 120 MHz. The device features dedicated reset logic with LVI (Low Voltage Interrupt), VLVI (Very Low Voltage Interrupt), and DCUTRST (deep-cut reset) for robust power monitoring across all supply domains.
