Product details

Overview

UPD78F1502AGK-GAK-M1-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/LF3 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 I²C, UART, and CSI interfaces, and targets embedded control in industrial sensors and motor drive subsystems.

For engineers reviewing the UPD78F1502AGK-GAK-M1-AX datasheet, UPD78F1502AGK-GAK-M1-AX pinout, UPD78F1502AGK-GAK-M1-AX application, or UPD78F1502AGK-GAK-M1-AX equivalent, key selection criteria include Flash endurance (100,000 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 UPD78F1502AGK-GAK-M1-AX implements the 78K0R CPU core with 16-bit ALU and 24-bit address space, enabling direct access to full 128 KB Flash and 8 KB RAM without banking. Its peripheral set includes a 16-bit multifunction timer array (with input capture, PWM output, and dead-time insertion), a watchdog timer with independent clock source, and a programmable 8-bit D/A converter.

Hardware-based serial communication is handled by three independent channels: one I²C-compatible interface supporting standard/fast mode (up to 400 kHz), two UARTs with LIN bus support and automatic baud rate detection, and one CSI interface compatible with SPI slave devices. All peripherals are managed via dedicated SFRs with interrupt capability and priority-level configuration.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R5F100LEAFB#30	Same 78K0R/LF3 family, identical pinout and peripheral set; differs only in Flash size (96 KB vs. 128 KB) and package marking.	Suitable where firmware footprint fits within 96 KB and no future feature expansion is planned.	Select when cost sensitivity outweighs need for firmware headroom or field upgrade capability.
UPD78F1501AGK-GAK-M1-AX	Direct sibling in same LF3 group; shares all peripherals but has 64 KB Flash and 4 KB RAM instead of 128 KB/8 KB.	Appropriate for simpler control tasks with smaller code base and lower RAM demand (e.g., basic timer-based sequencers).	Choose when application requires identical peripheral functionality but reduced memory resources suffice.

Compared with R5F100LEAFB#30 and UPD78F1501AGK-GAK-M1-AX, the UPD78F1502AGK-GAK-M1-AX provides 33% more Flash and 100% more RAM-critical for applications requiring OTA updates, cryptographic libraries, or multi-sensor fusion algorithms without external memory.

FAQ

What is the maximum operating frequency of the UPD78F1502AGK-GAK-M1-AX?

The UPD78F1502AGK-GAK-M1-AX supports a maximum system clock frequency of 20 MHz, achievable using either the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. At this speed, the 78K0R core delivers approximately 19.6 million instructions per second (MIPS), enabling deterministic real-time control loops with sub-microsecond timing resolution. The UPD78F1502AGK-GAK-M1-AX maintains full peripheral functionality-including ADC sampling and PWM generation-at rated frequency.

Does the UPD78F1502AGK-GAK-M1-AX include an integrated voltage regulator?

No, the UPD78F1502AGK-GAK-M1-AX does not integrate a DC-DC or LDO regulator. It requires externally supplied 2.7–5.5 V to VDD/VSS pins and separate analog supplies (AVDD0/AVSS) for the ADC and DAC blocks. This architecture allows system designers to select optimal external regulators based on noise, efficiency, and transient response requirements. The UPD78F1502AGK-GAK-M1-AX includes internal reset circuitry and voltage monitor (LVI) but relies on external regulation for clean power delivery.

Can the UPD78F1502AGK-GAK-M1-AX drive an LCD display directly?

Yes, the UPD78F1502AGK-GAK-M1-AX integrates a static/dynamic LCD controller supporting up to 8 commons and 24 segments (192 segments total). It provides programmable bias voltage generation, frame frequency control, and software-configurable duty cycle (1/2, 1/3, or 1/4). The UPD78F1502AGK-GAK-M1-AX drives common-electrode (COM) and segment-electrode (SEG) outputs directly-no external LCD driver IC is required for basic alphanumeric or icon-based displays in industrial HMIs.

What debug interface does the UPD78F1502AGK-GAK-M1-AX support?

The UPD78F1502AGK-GAK-M1-AX supports on-chip debugging via the single-wire FINE interface, compatible with Renesas' QB-MINI2 and E2 emulator tools. This interface enables full breakpoint control, register inspection, and flash programming without occupying any user I/O pins. The UPD78F1502AGK-GAK-M1-AX does not require JTAG or SWD; its FINE implementation uses dedicated pins (e.g., P10/P11) configured automatically during debug session initiation.

Is the UPD78F1502AGK-GAK-M1-AX qualified for automotive applications?

No, the UPD78F1502AGK-GAK-M1-AX is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial, office, and consumer applications-not automotive or safety-critical systems. It meets AEC-Q100 stress testing only if explicitly marked with automotive qualification suffixes (e.g., -GAK-A), which the UPD78F1502AGK-GAK-M1-AX does not carry. For automotive use, Renesas recommends the RL78/F13 or RH850 families instead.
