Block Diagram
Figure 1. The AT90S2313 Block Diagram
The AT90S2313 provides the following features: 2K bytes
of In-System Programmable Flash, 128 bytes EEPROM,
128 bytes SRAM, 15 general purpose I/O lines, 32 general
purpose working registers, flexible timer/counters with
compare modes, internal and external interrupts, a pro-
grammable serial UART, programmable Watchdog Timer
with internal oscillator, an SPI serial port for Flash Memory
downloading 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 reg-
ister contents but freezes the oscillator, disabling all other
chip functions until the next interrupt or hardware reset.
The device is manufactured using Atmel’s high density
non-volatile memory technology. The on-chip In-System
2
AT90S2313
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
AT90S2313 is a powerful microcontroller that provides a
highly flexible and cost effective solution to many embed-
ded control applications.
The AT90S2313 AVR is supported with a full suite of pro-
gram and system development tools including: C compil-
ers, macro assemblers, program debugger/simulators, in-
circuit emulators, and evaluation kits.
