onator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low
power consumption.
The device is manufactured using the Atmel high-density nonvolatile 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 program 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 opera-
tion. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel
AT90PWM216/316 is a powerful microcontroller that provides a highly flexible and cost effective solution to many
embedded control applications.
The AT90PWM216/316 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.
Note: AT90PWM216 device is available in SOIC 24-pin Package and does not have the D2A (DAC Output) brought out to I/0
pins.
3.2 Pin Descriptions
3.2.1 VCC
Digital supply voltage.
3.2.2 GND
Ground.
3.2.3
Port B (PB7..PB0)
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buf-
fers have symmetrical drive characteristics with both high sink and source capability. 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 running.
Port B also serves the functions of various special features of the AT90PWM216/316 as listed on page 63.
3.2.4
Port C (PC7..PC0)
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port C output buf-
fers have symmetrical drive characteristics with both high sink and source capability. 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 running.
Port C is not available on 24 pins package.
Port C also serves the functions of special features of the AT90PWM316 as listed on page 65.
3.2.5
Port D (PD7..PD0)
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output buf-
fers have symmetrical drive characteristics with both high sink and source capability. 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 running.
Port D also serves the functions of various special features of the AT90PWM216/316 as listed on page 68.
