Lecture#7-Memory, CPU Chips & Buses - 012443 | PDF | Dynamic Random Access Memory | Random ... This technique of data transfer is used when the speed of an i/o device does not match the speed of the microprocessor and also the timing characteristic of i/o device is not predictable. On chip ram, rom, i/o ports designer can decide on the amount of rom, ram and i/o ports. developed by intel in 1980 for use in embedded systems. four 8 bit i/o ports (p0 p3). what is embedded system? if not using any of the internal peripherals (timers) or external interrupts.

Block Diagram Of Microcontroller And Microprocessor - Your Desk Collection of 8 and 16 bit registers and 8 bit memory locations. external memory can be interfaced. vcc provides supply voltage to the chip. the voltage source is 5v. these 2 pins provide external clock. it is an input pin and is active high(normally low). The necessary tools for a microprocessor/controller • cpu: central processing unit • i/o: input /output • bus: address bus & data bus • memory: ram & rom • timer • interrupt • serial port • parallel port. Example: show the instructions to (a) enable the serial interrupt, timer 0 interrupt, and external hardware interrupt 1 and (b) disable (mask) the timer 0 interrupt, then (c) show how to disable all the interrupts with a single instruction. Port p0: when there is no external memory present, this port acts as a general purpose input/output port. in the presence of external memory, it functions as a multiplexed address and data bus.

Example: show the instructions to (a) enable the serial interrupt, timer 0 interrupt, and external hardware interrupt 1 and (b) disable (mask) the timer 0 interrupt, then (c) show how to disable all the interrupts with a single instruction. Port p0: when there is no external memory present, this port acts as a general purpose input/output port. in the presence of external memory, it functions as a multiplexed address and data bus. An 8051 microcontroller is an 8 bit harvard architecture microcontroller and it consists of a cpu, ram, rom, i/o ports, timers, and serial communication ports all combined on one chip. Step 1: places the content of data bus (4fh) in the ir and decode the instruction. step 2: transfer the content of the accumulator(82h) to the temporary register in the alu. Internal buses carry information within the processor, while external buses carry data between the processor and the memory. typically, the same data bus is used for both read/write operations. Overview of microcontrollers with a comparison of different mcus covering cpu, memory, i/o ports, timers, interrupts, and system bus.
