For engineers reviewing the UPD78F1502AGK-GAK-AX datasheet, UPD78F1502AGK-GAK-AX pinout, UPD78F1502AGK-GAK-AX application, or UPD78F1502AGK-GAK-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), on-chip voltage regulator support (REGC pin), and compliance with industrial temperature range (−40°C to +85°C) per Renesas quality grade "Standard".

Technical Context

The UPD78F1502AGK-GAK-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture separating program and data memory. It supports real-time interrupt handling via 16 priority-level vectors and includes dedicated hardware for PWM generation using Timer Array Unit (TAU) channels.

Its peripheral set is optimized for deterministic control loops: the 10-bit ADC features programmable sampling time and hardware-triggered conversion synchronized to timer overflow, while the on-chip voltage regulator (REGC) enables stable 3.3 V core supply from 4.0–5.5 V VDD input without external LDO.

FAQ

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

The UPD78F1502AGK-GAK-AX operates at a maximum system clock frequency of 20 MHz. This frequency is supported across the full industrial temperature range (−40°C to +85°C) and supply voltage range (4.0 V to 5.5 V). The clock source can be selected from the on-chip oscillator, external crystal (1–20 MHz), or external clock input, with configuration controlled via the system clock control registers in the SFR space.

Does the UPD78F1502AGK-GAK-AX include an on-chip voltage regulator?

Yes, the UPD78F1502AGK-GAK-AX includes an integrated voltage regulator controlled by the REGC pin. When a 1 μF ceramic capacitor is connected to REGC, the device generates a stable 3.3 V core supply from the main VDD rail (4.0–5.5 V), eliminating the need for an external LDO and simplifying power design in space-constrained applications.

How many ADC channels does the UPD78F1502AGK-GAK-AX support?

The UPD78F1502AGK-GAK-AX integrates a 10-bit successive approximation ADC with 16 input channels. These channels are mapped to dedicated analog pins (AN00–AN15) and support hardware triggering from timer overflow events, enabling precise, jitter-free sampling in real-time control loops without CPU intervention.

What package type is used for the UPD78F1502AGK-GAK-AX?

The UPD78F1502AGK-GAK-AX is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad. This package is RoHS-compliant and rated for industrial temperature operation (−40°C to +85°C), matching Renesas' "Standard" quality grade for use in office equipment, industrial robots, and test instrumentation.

Is the UPD78F1502AGK-GAK-AX pin-compatible with other members of the 78K0R/LF3 family?

Yes, the UPD78F1502AGK-GAK-AX shares identical pin configuration and electrical characteristics with other 78K0R/LF3 variants including μPD78F1500A and μPD78F1501A. All LF3 devices use the same 64-pin LQFP footprint, register-mapped peripherals, and memory map-enabling hardware reuse and firmware scalability across the family.
