ing the Registers, Timer/Counter, Watchdog and Interrupt system to continue

functioning. The Power-down mode saves the register contents but freezes the Oscilla-

tor, disabling all other chip functions until the next External Interrupt or hardware Reset.

The device is manufactured using Atmel’s high-density nonvolatile memory technology.

The On-chip In-System Programmable Flash allows the program memory to be repro-

grammed in-system through an SPI serial interface or by a conventional nonvolatile

memory programmer. By combining an enhanced RISC 8-bit CPU with In-System Pro-

g rammable Fla sh on a mo nolithic chip, th e Atme l AT90S1 200 is a p ower fu l

microcontroller that provides a highly flexible and cost-effective solution to many embed-

ded control applications.

The AT90S1200 AVR is supported with a full suite of program and system development

tools including: macro assemblers, program debugger/simulators, in-circuit emulators,

and evaluation kits.

Pin Descriptions

VCC

GND

Port B (PB7..PB0)

Supply voltage pin.

Ground pin.

Port B is an 8-bit bi-directional I/O port. Port pins can provide internal pull-up resistors

(selected for each bit). PB0 and PB1 also serve as the positive input (AIN0) and the

negative input (AIN1), respectively, of the On-chip Analog Comparator. The Port B out-

put buffers can sink 20 mA and thus drive LED displays directly. When pins PB0 to PB7

are used as inputs and are externally pulled low, they will source current if the internal

pull-up resistors are activated. The Port B pins are tri-stated when a reset condition

becomes active, even if the clock is not active.

Port B also serves the functions of various special features of the AT90S1200 as listed

on page 30.

Port D (PD6..PD0)

Port D has seven bi-directional I/O pins with internal pull-up resistors, PD6..PD0. The

Port D output buffers can sink 20 mA. As inputs, Port D pins that are externally pulled

low will source current if the pull-up resistors are activated. The Port D pins are tri-stated

when a reset condition becomes active, even if the clock is not active.

Port D also serves the functions of various special features of the AT90S1200 as listed

on page 34.

RESET

Reset input. A low level on this pin for more than 50 ns will generate a reset, even if the

clock is not running. Shorter pulses are not guaranteed to generate a reset.

Input to the inverting oscillator amplifier and input to the internal clock operating circuit.

Output from the inverting oscillator amplifier.
