By executing powerful instructions in a single clock cycle, the AT90S4414 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core is based on an enhanced RISC architecture that 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 one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

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 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 interrupt or hardware reset. 2 AT90S4414 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 embedded control applications. The AT90S4414 AVR is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, incircuit emulators, and evaluation kits. AT90S4414 Pin Descriptions VCC Supply voltage GND Ground Port A (PA7..PA0) Port A is an 8-bit bidirectional I/O port. Port pins can provide internal pull-up resistors (selected for each bit). The Port A output buffers can sink 20mA 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. Port A serves as Multiplexed Address/Data input/output when using external SRAM. Port B (PB7..PB0) Port B is an 8-bit bidirectional I/O pins 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. Port B also serves the functions of various special features of the AT90S4414 as listed on page 45. Port C (PC7..PC0) Port C is an 8-bit bidirectional 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. Port C also serves as Address output when using external SRAM. Port D (PD7..PD0) Port D is an 8-bit bidirectional 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. Port D also serves the functions of various special features of the AT90S4414 as listed on page 51. RESET Reset input. A low on this pin for two machine cycles while the oscillator is running resets the device. 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 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. Crystal Oscillator XTAL1 and XTAL2 are input and output, respectively, of an inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 2. Either a quartz crystal or a ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 3. Figure 2. Oscillator Connections Figure 3. External Clock Drive Configuration 3 AT90S4414 Architectural Overview The fast-access register file concept contains 32 x 8-bit general purpose working registers with a single clock cycle access time. This means that during one single clock cycle, one ALU (Arithmetic Logic Unit) operation is executed. Two operands are output from the register file, the operation is executed, and the result is stored back in the register file in one clock cycle. Six of the 32 registers can be used as three 16-bits indirect address register pointers for Data Space addressing - enabling efficient address calculations. One of the three address pointers is also used as the address pointer for the constant table look up function. These added function registers are the 16-bits X-register, Y-register and Z-register. Figure 4. The AT90S4414 AVR Enhanced RISC Architecture The ALU supports arithmetic and logic functions between registers or between a constant and a register. Single register operations are also executed in the ALU. Figure 4 shows the AT90S4414 AVR Enhanced RISC microcontroller architecture. In addition to the register operation, the conventional memory addressing modes can be used on the register file as well. This is enabled by the fact that the register file is assigned the 32 lowermost Data Space addresses ($00 $1F), allowing them to be accessed as though they were ordinary memory locations. The I/O memory space contains 64 addresses for CPU peripheral functions as Control Registers, Timer/Counters, 4 AT90S4414 A/D-converters, and other I/O functions. The I/O Memory can be accessed directly, or as the Data Space locations following those of the register file, $20 - $5F. The AVR uses a Harvard architecture concept - with separate memories and buses for program and data. The program memory is executed with a two stage pipeline. While one instruction is being executed, the next instruction is pre-fetched from the program memory. This concept enables instructions to be executed in every clock cycle. The program memory is in-system In-System Programmable Flash memory. With the relative jump and call instructions, the whole 2K address space is directly accessed. Most AVR instructions AT90S4414 have a single 16-bit word format. Every program memory address contains a 16- or 32-bit instruction. During interrupts and subroutine calls, the return address program counter (PC) is stored on the stack. The stack is effectively allocated in the general data SRAM, and consequently the stack size is only limited by the total SRAM size and the usage of the SRAM. All user programs must initialize the SP in the reset routine (before subroutines or inter- rupts are executed). The 16-bit stack pointer SP is read/write accessible in the I/O space. The 256 bytes data SRAM can be easily accessed through the five different addressing modes supported in the AVR architecture. The memory spaces in the AVR architecture are all linear and regular memory maps. Figure 5. Memory Maps A flexible interrupt module has its control registers in the I/O space with an additional global interrupt enable bit in the status register. All the different interrupts have a separate interrupt vector in the interrupt vector table at the beginning of the program memory. The different interrupts have priority in accordance with their interrupt vector position. The lower the interrupt vector address the higher priority. 5 AT90S4414 Register Summary 6 Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Page $3F ($5F) $3E ($5E) $3D ($5D) $3C ($5C) $3B ($5B) $3A ($5A) $39 ($59) $38 ($58) $37 ($57) $36 ($56) $35 ($55) $34 ($54) $33 ($53) $32 ($52) $31 ($51) $30 ($50) $2F ($4F) $2E ($4E) $2D ($4D) $2C ($4C) $2B ($4B) $2A ($4A) $29 ($49) $28 ($48) $27 ($47) $26 ($46) $25 ($45) $24 ($44) $23 ($43) $22 ($42) $21 ($41) $20 ($40) $1F ($3F) $1E ($3E) $1D ($3D) $1C ($3C) $1B ($3B) $1A ($3A) $19 ($39) $18 ($38) $17 ($37) $16 ($36) $15 ($35) $14 ($34) $13 ($33) $12 ($32) $11 ($31) $10 ($30) $0F ($2F) $0E ($2E) $0D ($2D) $0C ($2C) $0B ($2B) $0A ($2A) $09 ($29) $08 ($28) … $00 ($20) SREG SPH SPL Reserved GIMSK GIFR TIMSK TIFR Reserved Reserved MCUCR Reserved TCCR0 TCNT0 Reserved Reserved TCCR1A TCCR1B TCNT1H TCNT1L OCR1AH OCR1AL OCR1BH OCR1BL Reserved Reserved ICR1H ICR1L Reserved Reserved WDTCR Reserved Reserved EEAR EEDR EECR PORTA DDRA PINA PORTB DDRB PINB PORTC DDRC PINC PORTD DDRD PIND SPDR SPSR SPCR UDR USR UCR UBRR ACSR Reserved Reserved I SP15 SP7 T SP14 SP6 H SP13 SP5 S SP12 SP4 V SP11 SP3 N SP10 SP2 Z SP9 SP1 C SP8 SP0 19 20 20 INT1 INTF1 TOIE1 TOV1 INT0 INTF0 OCIE1A OCF1A - - - - - - OCIE1B OCF1B - TICIE1 ICF1 - TOIE0 TOV0 - 25 25 25 26 SRE SRW SE SM ISC11 ISC10 ISC01 ISC00 27 - - - CS02 CS01 CS00 30 31 CTC1 CS12 PWM11 CS11 PWM10 CS10 33 34 35 35 36 36 36 36 Timer/Counter0 (8 Bit) COM1A1 COM1A0 COM1B1 COM1B0 ICNC1 ICES1 Timer/Counter1 - Counter Register High Byte Timer/Counter1 - Counter Register Low Byte Timer/Counter1 - Output Compare Register A High Byte Timer/Counter1 - Output Compare Register A Low Byte Timer/Counter1 - Output Compare Register B High Byte Timer/Counter1 - Output Compare Register B Low Byte Timer/Counter1 - Input Capture Register High Byte Timer/Counter1 - Input Capture Register Low Byte - - EEPROM Address Register EEPROM Data Register PORTA7 PORTA6 DDA7 DDA6 PINA7 PINA6 PORTB7 PORTB6 DDB7 DDB6 PINB7 PINB6 PORTC7 PORTC6 DDC7 DDC6 PINC7 PINC6 PORTD7 PORTD6 DDD7 DDD6 PIND7 PIND6 SPI Data Register SPIF WCOL SPIE SPE UART I/O Data Register RXC TXC RXCIE TXCIE UART Baud Rate Register ACD - 36 36 - WDTOE WDE WDP2 WDP1 WDP0 - - - - - - PORTA5 DDA5 PINA5 PORTB5 DDB5 PINB5 PORTC5 DDC5 PINC5 PORTD5 DDD5 PIND5 PORTA4 DDA4 PINA4 PORTB4 DDB4 PINB4 PORTC4 DDC4 PINC4 PORTD4 DDD4 PIND4 PORTA3 DDA3 PINA3 PORTB3 DDB3 PINB3 PORTC3 DDC3 PINC3 PORTD3 DDD3 PIND3 EEMWE PORTA2 DDA2 PINA2 PORTB2 DDB2 PINB2 PORTC2 DDC2 PINC2 PORTD2 DDD2 PIND2 EEWE PORTA1 DDA1 PINA1 PORTB1 DDB1 PINB1 PORTC1 DDC1 PINC1 PORTD1 DDD1 PIND1 EERE PORTA0 DDA0 PINA0 PORTB0 DDB0 PINB0 PORTC0 DDC0 PINC0 PORTD0 DDD0 PIND0 DORD MSTR CPOL CPHA SPR1 SPR0 UDRE UDRIE FE RXEN OR TXEN CHR9 RXB8 TXB8 ACO ACI ACIE ACIC ACIS1 ACIS0 AT90S4414 39 40 40 41 54 54 54 56 56 56 61 61 61 63 63 63 46 45 45 49 49 50 52 53 AT90S4414 AT90S4414 Instruction Set Summary Mnemonics Operands Description ARITHMETIC AND LOGIC INSTRUCTIONS ADD Rd, Rr Add two Registers ADC Rd, Rr Add with Carry two Registers ADIW Rdl,K Add Immediate to Word SUB Rd, Rr Subtract two Registers SUBI Rd, K Subtract Constant from Register SBC Rd, Rr Subtract with Carry two Registers SBCI Rd, K Subtract with Carry Constant from Reg.
