AT90S1200-12SC

AT90S1200-12SC microcontroller is an 8-bit field programmed microcontroller manufactured by Atmel Corporation. It has been used in a wide variety of applications ranging from automotive, aerospace and industrial applications to consumer electronics and medical devices. The chip features a wide range of general purpose and special purpose I/O pins and supports a variety of communications protocols including Serial, I2C, Ethernet, USB, and SPI.

The AT90S1200-12SC microcontroller is specifically designed to operate in low power environments. The 8 bit core processor is based on the powerful Harvard architecture, allowing for quick and efficient execution of instructions. It has an 8 KB ROM, 2KB Flash memory and 1KB EEPROM. It also has an eight-bit ADC, two eight-bit timers, two Watchdogs, two UARTS and one serial SPI.

The AT90S1200-12SC is a single-chip 8-bit microcontroller which supports several peripheral devices such as a UART for serial communications, an SPI or I2C interface for data transfers and an EEPROM for non-volatile memory storage. The microcontroller can be programmed using an in-circuit programming tool connected to the JTAG interface. This allows the chip to be reprogrammed even after being installed in a system.

In applications where space is a constraint, the AT90S1200-12SC microcontroller offers features such as low power operation and low-cost manufacturing. It is also well suited for embedded systems with low-cost requirements and/or space-limited applications.

The AT90S1200-12SC microcontroller works on the basis of its architecture and its instruction set. The Harvard architecture is composed of two memories: a read-only memory (ROM) and a program memory (PROM). The controller hardware contains logic and an instruction set designed to address the interface logic, communication and interrupt logic, multiplexers and other hardware components. The instructions are stored in the program memory and are executed directly by the hardware. The instructions can be manipulated by the software, such as shifting the contents of a register, calculating an address from two values, or configuring hardware settings.

The chip has support for a broad range of peripherals, including dual UARTs, two-channel 16-bit timer, three-channel 8-bit timer, two-channel 8-bit analog/digital converters, two-channel 8-bit Pulse Width Modulation (PWM), two-channel 8-bit RTC, and two-channel serial peripheral interface (SPI). Additionally, the chip supports power saving modes, such as Stop mode and Sleep mode.

The AT90S1200-12SC microcontroller is a low-cost, low-power microcontroller which is ideal for embedded applications. Its wide range of peripherals, low power consumption, and small size make it a reliable choice for cost-sensitive, space-constrained applications. As such, the chip can be used not only in automotive, industrial, consumer electronics, and aerospace applications, but also in medical devices.
