FAQ

What is the maximum operating frequency of the UPD78F1518AGF(R)-GAT-M1-AX?

The UPD78F1518AGF(R)-GAT-M1-AX supports a maximum system clock frequency of 20 MHz when using the high-speed on-chip oscillator or an external crystal. This frequency is maintained across the full industrial temperature range (−40°C to +85°C) and supply voltage range (1.8 V to 5.5 V). The UPD78F1518AGF(R)-GAT-M1-AX achieves this performance while maintaining low power consumption in active and sleep modes.

Does the UPD78F1518AGF(R)-GAT-M1-AX include on-chip debug capability?

Yes, the UPD78F1518AGF(R)-GAT-M1-AX features a single-wire on-chip debug interface compliant with Renesas' standard SWD protocol. It supports real-time program execution control, memory inspection, register access, and breakpoint setting without halting the CPU. This debug capability is enabled by default and requires no external debug hardware beyond a compatible programmer such as the E2 emulator or QB-MINI2. The UPD78F1518AGF(R)-GAT-M1-AX does not require dedicated debug pins-debug signals share with P10/P11.

What analog peripherals are integrated into the UPD78F1518AGF(R)-GAT-M1-AX?

The UPD78F1518AGF(R)-GAT-M1-AX integrates a 10-bit successive approximation ADC with 16 input channels, a programmable voltage detector (PVD), and an on-chip voltage reference (VREFOUT). The ADC supports sampling rates up to 1 MSPS at 5 V and includes built-in offset calibration. The PVD monitors VDD with user-selectable thresholds (2.7 V typical), and VREFOUT provides a stable 2.5 V reference for ADC and comparator use. No external reference components are needed for basic metrology tasks in the UPD78F1518AGF(R)-GAT-M1-AX.

Is the UPD78F1518AGF(R)-GAT-M1-AX pin-compatible with other 78K0R/LH3 devices?

Yes, the UPD78F1518AGF(R)-GAT-M1-AX shares the same 100-pin LQFP package and pin assignment with other 78K0R/LH3 members including UPD78F1516AGF(R)-GAT-M1-AX and UPD78F1508AGF(R)-GAT-M1-AX. All LH3 variants maintain identical pin functions for power, reset, clock, debug, and peripheral I/O. Differences are limited to Flash size and minor peripheral enablement-ensuring PCB reuse across firmware variants. The UPD78F1518AGF(R)-GAT-M1-AX can be substituted on the same board without layout changes.

What is the Flash endurance specification for the UPD78F1518AGF(R)-GAT-M1-AX?

The UPD78F1518AGF(R)-GAT-M1-AX guarantees 100,000 write/erase cycles for its 128 KB on-chip Flash memory, validated under standard industrial conditions (25°C, VDD = 3.3 V). Each erase operation targets 128-byte blocks, enabling fine-grained firmware updates. Data retention is rated for 20 years at 85°C. These specifications are confirmed in Renesas' 78K0R/Lx3 Hardware User's Manual Rev.5.01 and apply directly to the UPD78F1518AGF(R)-GAT-M1-AX without derating.
