Microcontroller Chip

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.

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)

8-bit Microcontrollers - MCU 7KB 192 RAM 22 I/O. The 28-pin devices have three I/O ports.The 28-pin devices have fourteen interrupts

The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega48A/48PA/88A/88PA/168A/168PA/328/328P achieves through-puts approaching 1 MIPS per MHz allowing the system designer to optimise power consumption versus processing speed.
