Embedded - Microcontrollers

The AT90S4434-8JC microcontroller is an 8-bit, low-power integrated device used for embedded applications. It is equipped with 32Kbytes of on-chip Flash program memory and 1Kbyte of EEPROM. The device also features 128 bytes of data EEPROM, 256 bytes of RAM, 42 I/O lines, and a full range of on-chip peripherals and a 16 MIPS RISC core. The chip is compatible with the industry\'s leading microcontroller architectures such as I2C, SPI, and UART.The AT90S4434-8JC is used for embedded applications such as data acquisition, measurement, and control systems. It can be used for digital signal processing (DSP) applications as well, allowing for higher resolution and accuracy. The chip is also well suited for industrial and automotive applications which require low power consumption and long battery life.The AT90S4434-8JC uses a two-stage system to prove its operation. The first stage is the instruction execution cycle, which reads the application code from the on-chip program memory and executes it. During the second stage, the data memory and I/O are accessed via the data bus. Specifically, the data memory consists of 256 bytes of RAM and 128 bytes of data EEPROM.The I/O lines of the AT90S4434-8JC are grouped into four types of ports. The port A port contains 8 lines, the port B port has 16 lines, the port C contains 16 lines, and the port D port has 4. Each port features a programmable data direction and can be configured as input or output.The chip also comes with a range of on-chip peripherals. These include two 16-bit timer channels for timing and pulse-width modulation, three analog-to-digital converters, a 10-bit Low Voltage Programmable Timer, two UARTs, and two SPI ports.The AT90S4434-8JC is also a low-power device, which allows it to be used in battery-powered applications. The device requires less than 37mA of current when running at 16 MHz, and less than 8mA when running at 1.0 MHz. The chip also features a low power sleep mode and can run at 4 MHz with just 700uA of current.The AT90S4434-8JC is based on the AVR architecture, and is a very cost-effective solution for many embedded applications. It offers a large number of I/O lines, on-chip peripherals, and a low-power solution ideal for battery-powered applications. With its ease of use, the AT90S4434-8JC is a reliable, cost-effective solution for embedded applications.
