It operates at up to 20 MHz, supports I²C, UART, and CSI interfaces, and targets embedded control in industrial sensors and motor drive subsystems.

For engineers reviewing the UPD78F1500AGK(R)-GAK-M1-AX datasheet, UPD78F1500AGK(R)-GAK-M1-AX pinout, UPD78F1500AGK(R)-GAK-M1-AX application, or UPD78F1500AGK(R)-GAK-M1-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for low-power stop modes with wake-up via external interrupt or RTC alarm.

Technical Context

The UPD78F1500AGK(R)-GAK-M1-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a programmable 8-bit watchdog timer, 16-bit multi-function timer array (with input capture, output compare, PWM generation), and on-chip voltage regulator for internal logic supply.

It features a dedicated 10-bit ADC with sample-and-hold, selectable reference (AVREFP or internal bandgap), and automatic channel scanning. The device supports three power-saving modes - HALT, STOP, and SNOOZE - with wake-up latency as low as 4 µs from STOP mode using selected peripherals.

FAQ

What is the maximum operating frequency of the UPD78F1500AGK(R)-GAK-M1-AX?

The UPD78F1500AGK(R)-GAK-M1-AX supports a maximum system clock frequency of 20 MHz, achievable using either an external crystal (1–20 MHz) or the internal high-speed oscillator (16 MHz ±2%). At 20 MHz, the CPU executes instructions at 10 MIPS, with wait-state-free access to on-chip Flash and RAM.

Does the UPD78F1500AGK(R)-GAK-M1-AX include a hardware debug interface?

Yes, the UPD78F1500AGK(R)-GAK-M1-AX integrates a single-wire debug (SWD) interface accessible via P10 (SWCLK) and P11 (SWDIO) pins. This allows full in-circuit debugging, flash programming, and real-time register inspection using Renesas E2 studio or third-party tools compliant with ARM SWD protocol extensions.

How many ADC channels does the UPD78F1500AGK(R)-GAK-M1-AX support, and what is its resolution?

The UPD78F1500AGK(R)-GAK-M1-AX features a 10-bit successive-approximation ADC with 24 input channels (AN0–AN23). It supports programmable sampling time, automatic channel scanning, and conversion trigger sources including software, timer match, and external event, enabling synchronized acquisition in motor control applications.

What power-saving modes are available on the UPD78F1500AGK(R)-GAK-M1-AX?

The UPD78F1500AGK(R)-GAK-M1-AX supports three low-power modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RTC and LVD active), and SNOOZE (selected peripherals run while CPU sleeps). STOP mode draws ≤0.9 µA with RTC enabled and supports wake-up from 16 external pins or 8 internal sources.

Is the UPD78F1500AGK(R)-GAK-M1-AX pin-compatible with other 78K0R/LF3 devices?

Yes, the UPD78F1500AGK(R)-GAK-M1-AX shares identical 64-pin LQFP pinout and electrical characteristics with other 78K0R/LF3 variants (e.g., UPD78F1501A, UPD78F1502A), enabling hardware reuse across designs with differing Flash/RAM configurations or peripheral sets - provided PCB layout reserves space for optional components like external crystals or decoupling capacitors.
