Specifications of ATA6603-EK

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The AVR 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 throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The ATA6602/ATA6603 provides the following features: 8K/16K bytes of In-System Program-
mable Flash with Read-While-Write capabilities, 512 bytes EEPROM, 1 Kbyte SRAM,
23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Coun-
ters with compare modes, internal and external interrupts, a serial programmable USART, a
byte-oriented 2-wire Serial Interface, an SPI serial port, a 6-channel 10-bit ADC (8 channels in
TQFP and QFN packages), a programmable Watchdog Timer with internal Oscillator, and five
software selectable power saving modes. The Idle mode stops the CPU while allowing the
SRAM, Timer/Counters, USART, 2-wire Serial Interface, SPI port, and interrupt system to con-
tinue functioning. The Power-down mode saves the register contents but freezes the Oscillator,
disabling all other chip functions until the next 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 mod-
ules 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 sleep-
ing. This allows very fast start-up combined with low power consumption.
The device is manufactured using Atmel’s high density non-volatile memory technology. The
On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI
serial interface, by a conventional non-volatile memory programmer, or by an On-chip Boot pro-
gram 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 ATA6602/ATA6603 uses a powerful microcontroller that provides a
highly flexible and cost effective solution to many embedded control applications.
The ATA6602/ATA6603 AVR is supported with a full suite of program and system development
tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emu-
lator, and Evaluation kits.
4.2.2
Automotive Quality Grade
The ATA6602 and ATA6603 have been developed and manufactured according to the most
stringent requirements of the international standard ISO-TS-16949 grade 1. This data sheet con-
tains limit values extracted from the results of extensive characterization (Temperature and
Voltage). The quality and reliability of the ATA6602 and ATA6603 have been verified during reg-
ular product qualification as per AEC-Q100.
