The AT90S4414 Block Diagram
The AT90S4414 provides the following features: 4K bytes
of In-System Programmable Flash, 256 bytes EEPROM,
256 bytes SRAM, 32 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 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
interrupt or hardware reset.
The device is manufactured using Atmel’s high density
non-volatile 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
AT90S4414 is a powerful microcontroller that provides a
highly flexible and cost effective solution to many embed-
ded control applications.
The AT90S4414 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.
