The PIC16F873, PIC16F874, PIC16F876 and PIC16F877 are the four covered devices. Devices for the PIC16F876/873 and PIC16F877/874 available in 28-pin and 40-pin packages, respectively. On 28-pin devices, the Parallel Slave Port is not implemented.
Each PIC16F87X device has the ability to access an 8K word block of programme memory continuously. Only 11 bits of address are provided by the CALL and GOTO instructions, allowing branching inside any 2K programme memory page. PCLATH4:3> provides the upper 2 bits of the address when performing a CALL or GOTO instruction. The user must make sure that the page choose bits are set when performing a CALL or GOTO instruction in order for the chosen programme memory page to be addressed. The full 13-bit PC is popped off the stack whenever a return from a CALL instruction (or interrupt) is performed. Therefore, the return instructions do not need the modification of the PCLATH4:3> bits (which POPs the address from the stack)

The Arm® Cortex®-M group of processor cores is a series of cores optimized for power efficiency and deterministic operation. It is widely used in microcontrollers (MCUs) and can also be found embedded into multi-core microprocessors (MPUs).

The AT89S52 includes the following features as standard: 8K bytes of flash memory, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock hardware are all included. Furthermore, the AT89S52 features static logic for operating at low frequencies and two software-selectable power-saving modes. The CPU is turned down in Idle Mode, while the RAM, timers/counters, serial port, and alarm system remain operational. The RAM contents are saved in Power-down mode, but the oscillator is frozen, blocking all other chip functions until the next signal or hardware reset.

This PIC® architecture-based CMOS FLASH-based 8-bit microcontroller is upward compatible with the PIC16C5X, PIC12CXXX, and PIC16C7X devices and is powerful (200 millisecond instruction execution) yet simple to programme (just 35 single word instructions). The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial interface that can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). These attributes make it perfect for higher level A/D applications in the automotive, industrial, appliance, and consumer markets.

There are multiple devices in the Texas Instruments MSP430 family of ultra-low-power microcontrollers, each of which has a unique set of peripherals designed for a particular purpose. In portable measurement applications, the design is tailored to achieve longer battery life through the use of five low-power modes. The system has a potent 16-bit RISC CPU, 16-bit registers, and constant generation that help the code run as efficiently as possible. In less than one second, the digitally controlled oscillator (DCO) enables wake-up from low-power modes to active mode. The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with integrated 16-bit timers, up to 24 I/O capacitive-touch enabled pins, a flexible analogue comparator, and integrated communication utilising the universal serial communication interface.The MSP430G2x53 family members also have an analog-to-digital (A/D) converter with a 10-bit resolution. Low-cost sensor systems that gather analogue signals, transform them into digital values, and then process the data for display or transmission to a host system are common uses.

Entire Series of microcontrollers is available with us.

A low-voltage, high-performance CMOS 8-bit microprocessor called the AT89C2051 has 2K bytes of Flash PEROM, or programmable and erasable read-only memory. The system is made with high-density nonvolatile memory technology from Atmel, and it is compatible with the widely used MCS-51 instruction set. The Atmel AT89C2051 is a potent microcomputer that offers a highly flexible and affordable solution to many embedded control applications by fusing a flexible 8-bit CPU with Flash on a monolithic device.
