UPD78F1013GF-GAS-AX

The UPD78F1013GF-GAS-AX series is a highly integrated, industry-leading family of 8-bit microcontrollers from Renesas that have been designed for optimal performance in automotive applications. The series is comprised of three variants of the same core device with slight differences in each variant’s instruction set and peripheral features. As a result, each variant is dedicated to different application fields configured to best suit their particular needs.

The main components of the UPD78F1013GF-GAS-AX series constitute of a CPU unit, a program RAM (PRAM), a data RAM (DRAM), an interrupt controller (INTC), an on-chip hardware debugger (HWD), a real-time clock (RTC) module and a serial communications interface (SCI). All the mentioned modules are highly integrated inside the microcontroller and feature support for a variety of communication protocols, configurations, and advanced digital signal processing (DSP) functions. As a result, it makes the series a suitable choice for applications involving sensor processing, image processing and motor control.

The CPU of the UPD78F1013GF-GAS-AX series is based on the single-chip 8-bit C80 instruction set which is well suited for most embedded applications. The CPU also features power saving functions such as Idle mode, Halt mode, and reduced clock speed support. These features enable the microcontroller to limit its power consumption when the workload is low, and increase it when the system needs more processing power.

The on-chip program RAM (PRAM) features an integral stack to store executed programs and variables, as well as a scratchpad memory to store temporary variables. The data RAM (DRAM) has a wide range of uses, including general-purpose system RAM, display and data buffering, interrupt table, I/O ports, and stack and scratchpad memory. The interrupt controller (INTC) supports priority-based interrupt handling and provides a total of 8 priority levels. It also allows for interrupts to be triggered either by a hardware or a software source.

The UPD78F1013GF-GAS-AX series also has an on-chip HWD (Hardware Debugger) which can be used for debugging the application. The HWD supports a number of functions to help reduce time spent developing an application, including an instruction trace history, a data trace history, memory view DMA, and breakpoints. The real-time clock (RTC) module can be used to measure time periods down to an accuracy of 1 millisecond. It also supports an alarm interrupt, a periodic wake-up signal, and a power-on reset function.

The serial communications interface (SCI) of the UPD78F1013GF-GAS-AX series supports both RS-232 and RS-485 protocols. It also features support for I2C, SPI and CAN communication busses. This makes the SCI a suitable choice for applications with sensor nodes and long-distance communication requirements.

In conclusion, the UPD78F1013GF-GAS-AX series has been designed to be an optimal choice for applications requiring low power consumption and optimal performance. The series has been tailored to the needs of automotive applications, and the various components enable it to cover most common sensing, signaling and communication procedures. The on-chip debug support and the RTC module make the series a suitable choice for real-time and time-sensitive applications, while the support for various communication protocols enable the series to be used in more complex applications.
