AT90S1200
0838HS–AVR–03/02
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 toberepro-
grammed in-system throughan SPI serial interface or by a conventional nonvolatile
memory programmer. By combining an enhanced RISC 8-bit CPU with In-System Pro-
g ram m abl e F la sh on a mo nol ithi c chi p, th e Atme l AT 90S1 200 is a p ower ful
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.
PinDescriptions
VCC
Supply voltagepin.
GND
Ground pin.
Port B(PB7..PB0)
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 AnalogComparator. The Port B out-
put buffers can sink 20 mA and thus drive LED displays directly. When pins PB0to PB7
areusedas inputs andare 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 page30.
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 page34.
RESET
Reset input. A low level on this pin for more than 50ns will generate a reset, even if the
clock is not running. Shorter pulses are not guaranteed to generate a reset.
XTAL1
Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
XTAL2
Output from the inverting oscillator amplifier.
