Comparison between Atmel ATtiny87 and Atmel ATtiny167
Part Description

Atmel ATtiny87 and Atmel ATtiny167 are hardware and software compatible. They differ only
in memory sizes as shown in
Table 4-1.
The Atmel
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
Atmel ATtiny87/167 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
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 inde-
pendent 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 conventional CISC microcontrollers.
The Atmel ATtiny87/167 provides the following features: 8K/16K byte of In-System Program-
mable Flash, 512bytes EEPROM, 512bytes SRAM, 16 general purpose I/O lines, 32 general
purpose working registers, one 8-bit Timer/Counter with compare modes, one 8-bit high speed
Timer/Counter, Universal Serial Interface, a LIN controller, Internal and External Interrupts, a
11-channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, and three
software selectable power saving modes. The Idle mode stops the CPU while allowing the
SRAM, Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue function-
ing. The Power-down mode saves the register contents, disabling all chip functions until the
next Interrupt or Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O
modules except ADC, to minimize switching noise during ADC conversions.
The device is manufactured using Atmel’s high density non-volatile memory technology. The
On-chip ISP Flash allows the Program memory to be re-programmed In-System through an
SPI serial interface, by a conventional non-volatile memory programmer or by an On-chip boot
code running on the AVR core. The Boot program can use any interface to download the appli-
cation program in the Flash memory.
