Product details
Overview
UPD78F0887AGKA-GAJ-G from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/Fx2-L family, featuring 128 KB Flash memory, 8 KB RAM, and a 20 MHz max CPU clock. It integrates UART, I²C, 16-bit timer/counters, ADC (10-bit, 12-channel), and on-chip voltage regulator (REGC). It targets industrial control and sensor interface applications requiring low-power operation and robust peripheral integration.
For engineers reviewing the UPD78F0887AGKA-GAJ-G datasheet, UPD78F0887AGKA-GAJ-G pinout, UPD78F0887AGKA-GAJ-G application, or UPD78F0887AGKA-GAJ-G equivalent, key selection criteria include its 30-pin LQFP package, internal high-/low-speed oscillators, Flash self-programming capability, and support for both standard and high-quality grade applications per Renesas classification.
Technical Context
The UPD78F0887AGKA-GAJ-G implements the 78K0 CPU core with 16-bit addressing, supporting up to 1 MB linear address space via bank switching. Its clock system includes three independent oscillators - external crystal (X1), internal high-speed (16 MHz), and internal low-speed (15 kHz) - selectable via software-controlled registers with automatic fail-safe switching.
Peripheral integration follows the 78K0/Fx2-L architecture: 12-channel 10-bit ADC with sample-and-hold, dual UARTs with LIN support, I²C master/slave mode, and six 16-bit timer/counters with capture/compare/PWM output. All peripherals are memory-mapped and controlled via dedicated SFRs with interrupt vectoring.

FAQ
What is the maximum operating frequency of the UPD78F0887AGKA-GAJ-G?
The UPD78F0887AGKA-GAJ-G supports a maximum system clock frequency of 20 MHz. This can be achieved using the on-chip PLL with an external crystal (X1) or internal high-speed oscillator as source. The CPU executes instructions at this frequency, and all peripherals-including ADC sampling and UART baud generation-are synchronized to this clock domain unless prescaled.
Does the UPD78F0887AGKA-GAJ-G include an integrated voltage regulator?
Yes, the UPD78F0887AGKA-GAJ-G features an on-chip voltage regulator controlled via the REGC pin. When enabled, it generates a regulated 3.3 V supply from an external 4.5–5.5 V input applied to REGC, powering the internal VDD domain. This eliminates the need for an external LDO in many industrial designs, simplifying BOM and reducing board area.
Which communication interfaces does the UPD78F0887AGKA-GAJ-G support?
The UPD78F0887AGKA-GAJ-G supports UART (two channels, with UART1 offering LIN 2.1/2.2 physical layer modulation), I²C (master/slave mode), and CSI (synchronous serial interface). It does not include SPI or CAN. UART0 and UART1 are independently configurable with separate baud rate generators and interrupt vectors, enabling concurrent use for debugging and fieldbus communication.
How much Flash and RAM does the UPD78F0887AGKA-GAJ-G have?
The UPD78F0887AGKA-GAJ-G integrates 128 KB of on-chip Flash memory and 8 KB of RAM. Flash endurance is rated for 100,000 write/erase cycles and supports in-application programming (IAP) via the built-in Flash control module. RAM retains data during STOP mode when powered, enabling fast wake-up with preserved context.
Is the UPD78F0887AGKA-GAJ-G qualified for automotive applications?
No, the UPD78F0887AGKA-GAJ-G is classified by Renesas as a "Standard" quality grade device, intended for industrial, office, and consumer equipment-not transportation or safety-critical systems. It is not AEC-Q100 qualified. For automotive use, Renesas recommends RL78/F1x or RH850 families, which meet AEC-Q100 Grade 2/3 requirements and include extended temperature range and fault-tolerant features.
