ATMega32A 8-Bit 40-Pin AVR MCU Microcontroller Best Price in Pakistan

ATMega32A 8-Bit 40-Pin AVR MCU Microcontroller Best Price in Pakistan .core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving through puts up to ten times faster than conventional CISC micro-controllers.

Features of ATMega32A 8-Bit 40-Pin AVR MCU Microcontroller :

The ATMega32A 8-Bit 40-Pin AVR MCU Microcontroller Best Price in Pakistan provides the following features:

32Kbytes of In-System Programmable Flash Program memory with Read-While-Write capabilities

1024bytes EEPROM

2Kbyte SRAM

32 general purpose I/O lines

32 general purpose working registers

a JTAG interface for Boundary scan

On-chip Debugging support and programming

three flexible Timer/Counters with compare modes

Internal and External Interrupts

a serial programmable USART

a byte oriented Two-wire Serial Interface

an 8-channel, 10-bit ADC with optional differential input stage with programmable gain (TQFP package only)

a programmable Watchdog Timer with Internal Oscillator

an SPI serial port

and six software selectable power saving modes.

Uses:

The Idle mode stops the CPU while allowing the USART, Two-wire interface. A/D Converter, S-RAM, Timer/Counters, SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator. disabling all other chip functions until the next External Interrupt or Hardware Reset. In Power-save mode, the Asynchronous Timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O modules except Asynchronous Timer and ADC, to minimize switching noise during ADC conversions. In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping.

Consumption:

This allows very fast start-up combined with low-power consumption. In Extended Standby mode, both the main Oscillator and the Asynchronous Timer continue to run. The device is manufactured using Atmel’s high density nonvolatile memory technology. The Onchip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface. by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated. providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip. the Atmel ATmega32 is a powerful microcontroller that provides a highly-flexible .  and cost-effective solution to many embedded control applications.
