AT90S8515

Description The AT90S8515 is a low-power CMOS 8-bit microcontroller based on the AVR RISC

architecture. By executing powerful instructions in a single clock cycle, the AT90S8515
achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to
optimize power consumption versus processing speed.

0841GS–09/01

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

Pin Descriptions

one clock cycle. The resulting architecture is more code efficient while achieving
throughputs up to ten times faster than conventional CISC microcontrollers.

The AT90S8515 provides the following features: 8K bytes of In-System Programmable
Flash, 512 bytes EEPROM, 512 bytes SRAM, 32 general-purpose I/O lines, 32 general­purpose working registers, flexible timer/counters with compare modes, internal and
external interrupts, a programmable serial UART, programmable Watchdog Timer with
internal oscillator, an SPI serial port and two software-selectable power-saving modes.
The Idle Mode stops the CPU while allowing the 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.

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 repro­grammed 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 Pro­grammable Flash on a monolithic chip, the Atmel AT90S8515 is a powerful
microcontroller that provides a highly flexible and cost-effective solution to many embed­ded control applications.

The AT90S8515 AVR is supported with a full suite of program and system development
tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit
emulators and evaluation kits.

VCC Supply voltage.

GND Ground.

Port A (PA7..PA0) Port A is an 8-bit bi-directional I/O port. Port pins can provide internal pull-up resistors

(selected for each bit). The Port A output buffers can sink 20 mA and can drive LED dis­plays directly. When pins PA0 to PA7 are used as inputs and are externally pulled low,
they will source current if the internal pull-up resistors are activated. The Port A pins are
tri-stated when a reset condition becomes active, even if the clock is not active.

Port A serves as multiplexed address/data input/output when using external SRAM.

Port B (PB7..PB0) Port B is an 8-bit bi-directional I/O port with internal pull-up resistors. The Port B output

buffers can sink 20 mA. As inputs, Port B pins that are externally pulled low will source
current if the 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 AT90S8515 as listed
on page 66.

Port C (PC7..PC0) Port C is an 8-bit bi-directional I/O port with internal pull-up resistors. The Port C output

buffers can sink 20 mA. As inputs, Port C pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset
condition becomes active, even if the clock is not active.

Port C also serves as address output when using external SRAM.

Port D (PD7..PD0) Port D is an 8-bit bi-directional I/O port with internal pull-up resistors. 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 AT90S8515 as listed
on page 73.

RESET

XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit.

XTAL2 Output from the inverting oscillator amplifier.

ICP ICP is the input pin for the Timer/Counter1 Input Capture function.

OC1B OC1B is the output pin for the Timer/Counter1 Output CompareB function.

ALE ALE is the Address Latch Enable used when the External Memory is enabled. The ALE

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.

strobe is used to latch the low-order address (8 bits) into an address latch during the first
access cycle, and the AD0 - 7 pins are used for data during the second access cycle.

Notes: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses

should never be written.

2. Some of the status flags are cleared by writing a logical “1” to them. Note that the CBI and SBI instructions will operate on all
bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions work
with registers $00 to $1F only.
