It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1009F1(S)-AN1-A datasheet, UPD78F1009F1(S)-AN1-A pinout, UPD78F1009F1(S)-AN1-A application, or UPD78F1009F1(S)-AN1-A equivalent, key selection considerations include its 64-pin LQFP package, 10-bit ADC resolution with sample-and-hold, dual voltage domains (EVDD/EVSS for analog section), and support for on-chip self-programming via FLMD0 configuration.
Technical Context
The UPD78F1009F1(S)-AN1-A implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 16-bit multifunction timer (TM00–TM03) with capture/compare and PWM output capability, plus a watchdog timer with independent clock source.
Analog subsystem includes a 10-bit successive-approximation ADC with internal reference (AVREF), programmable sampling time, and automatic channel scanning. Digital I/O supports 52 general-purpose pins across ports P0–P8 and P12–P15, with selectable pull-up resistors and CMOS-level input thresholds.

FAQ
What is the maximum operating frequency of the UPD78F1009F1(S)-AN1-A?
The UPD78F1009F1(S)-AN1-A supports a maximum system clock frequency of 20 MHz. This is achieved using either the on-chip oscillator (tunable from 1 to 20 MHz) or an external crystal/resonator connected to P00/P01. At 20 MHz, the CPU executes instructions with single-cycle access to on-chip RAM and two-cycle access to Flash memory, enabling deterministic real-time response in motor control and sensor acquisition loops.
Does the UPD78F1009F1(S)-AN1-A support in-system programming?
Yes, the UPD78F1009F1(S)-AN1-A supports in-system programming via its built-in bootloader. When FLMD0 is held low at power-on, the device enters flash programming mode and accepts commands over UART0. This enables field firmware updates without removing the UPD78F1009F1(S)-AN1-A from the PCB, and eliminates the need for external programming hardware during production or maintenance.
How many ADC channels does the UPD78F1009F1(S)-AN1-A have, and what is their resolution?
The UPD78F1009F1(S)-AN1-A integrates a 10-bit successive-approximation ADC with 16 input channels. These channels are mapped across ports P2, P3, P4, and P5, and support automatic scanning, software-triggered conversion, and external event triggering (e.g., timer match). The ADC uses a dedicated analog voltage domain (EVDD/EVSS) to maintain accuracy under digital switching noise, delivering ±1 LSB INL and DNL over the full operating temperature range.
What package type is used for the UPD78F1009F1(S)-AN1-A?
The UPD78F1009F1(S)-AN1-A is supplied in a 64-pin LQFP package with dimensions 10 mm × 10 mm and 0.5 mm lead pitch (suffix AN1-A). This package includes an exposed thermal pad on the underside for improved heat dissipation and is RoHS-compliant. Pin assignments follow the 78K0R/KE3-L standard layout documented in Renesas User's Manual R01UH0106EJ0400, Section 1.4.3.
Which development tools are compatible with the UPD78F1009F1(S)-AN1-A?
The UPD78F1009F1(S)-AN1-A is supported by Renesas' legacy 78K0R toolchain: CC78K0R C compiler (Ver. 2.00), RA78K0R assembler (Ver. 1.20), and QB-MINI2 on-chip debug emulator. It is also compatible with the QB-78K0RIX3 in-circuit emulator, which supports the full 78K0R/KC3-L through KE3-L families. Firmware debugging and flash programming are enabled via the on-chip debug interface using standard SWD-like protocols.
