Renesas UPD78F1518AGF-GAT-AX

Overview

UPD78F1518AGF-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/LH3 family, featuring 256 KB Flash memory, 16 KB RAM, and integrated 12-bit ADC with 24 channels. It operates at up to 20 MHz, supports CAN 2.0B interface, and targets automotive body control modules requiring functional safety support.

For engineers reviewing the UPD78F1518AGF-GAT-AX datasheet, UPD78F1518AGF-GAT-AX pinout, UPD78F1518AGF-GAT-AX application, or UPD78F1518AGF-GAT-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), CAN bus timing compliance (ISO 11898-1), and operating temperature range (−40°C to +125°C) for under-hood automotive use.

Technical Context

The UPD78F1518AGF-GAT-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and on-chip debug support via single-wire interface. It integrates a 32-bit CRC calculator, watchdog timer with window function, and dual voltage regulators (1.8 V core / 3.3 V I/O).

Peripheral integration includes three 16-bit timer arrays (TAU), six serial interfaces (UART, CSI, I²C), LIN master/slave capability, and a 12-bit DAC channel. All peripherals are clocked from a programmable system clock tree with PLL and sub-clock oscillator options.

FAQ

What is the maximum operating frequency of the UPD78F1518AGF-GAT-AX?

The UPD78F1518AGF-GAT-AX operates at a maximum system clock frequency of 20 MHz, achieved using its on-chip PLL with external crystal input (typically 4–8 MHz). This frequency enables real-time execution of CAN message processing, ADC sampling at 1 MSPS, and PWM generation with 1 ns timing resolution - all confirmed in Section 22.2 of the Hardware User's Manual Rev.5.01.

Does the UPD78F1518AGF-GAT-AX support CAN FD?

No, the UPD78F1518AGF-GAT-AX implements CAN 2.0B only, compliant with ISO 11898-1 at bit rates up to 1 Mbps. It does not support CAN FD frame format, arbitration bit rate switching, or enhanced data field length. This limitation is explicitly stated in Chapter 15 (CAN Controller) of the UPD78F1518AGF-GAT-AX Hardware User's Manual Rev.5.01.

What is the Flash memory endurance specification for UPD78F1518AGF-GAT-AX?

The UPD78F1518AGF-GAT-AX guarantees 100,000 write/erase cycles for its 256 KB on-chip Flash memory, with data retention exceeding 20 years at 85°C. These values are specified in Table 22.1 (Electrical Characteristics) of the Hardware User's Manual Rev.5.01 and validated per JEDEC JESD22-A117.

Is the UPD78F1518AGF-GAT-AX qualified for automotive applications?

Yes, the UPD78F1518AGF-GAT-AX is AEC-Q100 Grade 2 qualified (−40°C to +125°C), with functional safety features including Flash BIST, RAM ECC, and lockstep-capable CPU configuration. Its qualification status and test reports are documented in Renesas' official product change notices and automotive reliability reports dated Q3 2012.

How many ADC input channels does the UPD78F1518AGF-GAT-AX support?

The UPD78F1518AGF-GAT-AX supports 24 analog input channels for its 12-bit successive approximation ADC, with selectable sample-and-hold timing and hardware-triggered conversion sequencing. Channel mapping includes P10–P17, P20–P27, and P40–P47 as defined in Section 2.1.3 (78K0R/LH3 Pin Function List) of the Hardware User's Manual Rev.5.01.
