The ATmega 32A provides the following features:

32Kbytes of In-System Programmable Flash Program memory with Read-While-Write capabilities,
1024bytes EEPROM,
2048bytes 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.

The Idle mode stops the CPU while allowing the USART, Two-wire interface, A/D Converter, SRAM, 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. 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 On-chip 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 ATmega32A is a powerful microcontroller that provides a highly-flexible and cost-effective solution to many embedded control applications.
