FAQ

What is the maximum operating frequency of the UPD78F1016F1(R)-BA4-A?

The UPD78F1016F1(R)-BA4-A supports a maximum system clock frequency of 20 MHz when using the internal high-speed oscillator with appropriate prescaling. Its 78K0R CPU core executes instructions at up to 16 MHz effective speed, with key peripherals like timers and ADC synchronized to this clock domain. The device also supports external crystal (X1) and ceramic resonator (XT1) inputs for precision timing.

Does the UPD78F1016F1(R)-BA4-A include on-chip debug support?

Yes, the UPD78F1016F1(R)-BA4-A integrates on-chip debugging capability compatible with Renesas' QB-MINI2 emulator and ID78K0R-QB debugger. It supports full breakpoint, watchpoint, and memory/register inspection via the single-wire debug interface (SWD), eliminating the need for external JTAG hardware and reducing development board footprint.

What power supply configurations does the UPD78F1016F1(R)-BA4-A support?

The UPD78F1016F1(R)-BA4-A operates from a single 2.7–5.5 V supply applied to VDD/VSS, with internal regulation provided via the REGC pin to generate a stable 3.3 V core voltage. It separates analog (AVDD/AVSS) and digital (VDD/VSS) power domains and includes dedicated pins for VREFOUT and AVREFP to ensure ADC accuracy independent of main supply fluctuations.

How many ADC channels does the UPD78F1016F1(R)-BA4-A provide, and what is their resolution?

The UPD78F1016F1(R)-BA4-A features a 10-bit successive-approximation ADC with 16 selectable input channels. These channels are distributed across Ports P1, P2, and P4, and support simultaneous sampling via internal multiplexer control. The ADC includes built-in offset calibration and uses the internal 2.5 V reference (VREFOUT) for consistent full-scale accuracy across temperature and supply variations.

Is the UPD78F1016F1(R)-BA4-A pin-compatible with other devices in the 78K0R/Kx3-A family?

Yes, the UPD78F1016F1(R)-BA4-A shares identical pinout and package (64-pin LQFP) with UPD78F1017F1(R)-BA4-A and UPD78F1018F1(R)-BA4-A. This allows direct substitution for memory-scaling purposes - for example, upgrading from 128 KB to 192 KB Flash - without PCB redesign, provided peripheral usage and timing margins remain within specification limits for the target variant.
