• Application Field

The MB91248SZPFV-GS-138K5E1 is an 8-bit product of Fujitsu Semiconductor. It is an embedded microcontroller designed for low-cost and low-power applications. It is designed for energy-efficient applications such as home appliances, handheld electronics, and medical devices.

The MB91248SZPFV-GS-138K5E1 was developed to meet the needs of applications such as intelligent control, display control, power management, and sensor control. It is designed for an operation temperature range of -40°C to 85°C and low power operation, making it suitable for use in environments with limited power supply. Additionally, it has a small memory capacity with 1K×16 words, 128 bytes of on-chip RAM, and 16K bytes of on-chip Flash memory.

In addition to its wide operating temperature range and low power consumption, it also offers functionality such as high speed, large memory capacity, and serial interface. The MB91248SZPFV-GS-138K5E1 is ideal for applications that require small size, low cost, and low power such as consumer appliances and hearing aids.

• Working Principle

The MB91248SZPFV-GS-138K5E1 is an 8-bit microcontroller architecture. It is based on a Harvard architecture with two buses, an internal bus and an external bus. The external bus is used for external memory access, whereas the internal bus is used for access to the internal data memory and program memory. The internal bus is also used for access to internal peripherals, such as timers and serial ports.

The MB91248SZPFV-GS-138K5E1 has both an on-chip Flash memory and an on-chip RAM. The Flash memory is used to store the program code and data. The RAM is used as both a storage space for data and as a stack memory. The embedded RAM is used as the stack memory. This ensures that the data stack is always available.

The MB91248SZPFV-GS-138K5E1 includes an instruction set with added instructions optimized for low power operation. It is also programmed by a software toolchain. The programming environment includes an integrated development environment (IDE) for programming in assembly language and a software debugger for debugging the application.

The MB91248SZPFV-GS-138K5E1 offers a wide range of analog and digital peripherals. It has two serial ports, two timer blocks, two or four 8-bit general-purpose I/O ports, one 8-bit dual-purpose port which can be configured as input port or output port, and one analog-to-digital converter. It also includes an 8-bit watchdog timer, a 16-bit watchdog timer, an 8-bit timer, an 8-bit pulsewidth modulator, an 8-bit pulsewidth detector, and a 4-bit input capture.

The MB91248SZPFV-GS-138K5E1 has a wide range of applications in the field of embedded microcontrollers. It is designed for energy-efficient applications such as home appliances, handheld electronics, and medical devices. It is designed for an operation temperature range of -40°C to 85°C and low power operation, making it suitable for use in environments with limited power supply. Additionally, it has a small memory capacity with 1K×16 words, 128 bytes of on-chip RAM, and 16K bytes of on-chip Flash memory.
