IN90S2333DW, IN90LS2333DW, 8-BIT MICROCONTROLLER WITH 2K/4K BYTES BUILD-IN PROGRAMMABLE FLASH Description The IN90S2333 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By 28 executing powerful instructions in a single clock cycle, the IN90S2333 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. 1 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 one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The AT90S2333/4433 provides the following features: 2K/4K bytes of In-System Programmable Flash, 128/256 bytes EEPROM, 128 bytes SRAM, 20 general purpose I/O lines, 32 general purpose working registers, two flexible timer/counters with compare modes, internal and external interrupts, a programmable serial UART, 6-channel, 10-bit ADC, 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 nonvolatile memory technology. The on-chip Flash program memory can be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer. By combining a RISC 8-bit CPU with In-System Programmable Flash on a monolithic chip, the Atmel AT90S2333/4433 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The AT90S2333/4433 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. 1 IN90S2333DW, IN90LS2333DW, Features • High-performance and Low-power AVR® 8-bit RISC Architecture – 118 Powerful Instructions - Most Single Cycle Execution – 32 x 8 General Purpose Working Registers – Up to 8 MIPS Throughput at 8 MHz • Data and Nonvolatile Program Memory – 2K/4K Bytes of In-System Programmable Flash Endurance 1,000 Write/Erase Cycles – 128 Bytes of SRAM – 128/256 Bytes of In-System Programmable EEPROM Endurance: 100,000 Write/Erase Cycles – Programming Lock for Flash Program and EEPROM Data Security • Peripheral Features – One 8-bit Timer/Counter with Separate Prescaler – Expanded 16-bit Timer/Counter with Separate Prescaler, Compare, Capture Modes and 8-, 9- or 10-bit PWM – On-chip Analog Comparator – Programmable Watchdog Timer with Separate On-chip Oscillator – Programmable UART – 6-channel, 10-bit ADC – Master/Slave SPI Serial Interface • Special Microcontroller Features – Brown-Out Reset Circuit – Enhanced Power-on Reset Circuit – Low-Power Idle and Power Down Modes – External and Internal Interrupt Sources • Specifications – Low-power, High-speed CMOS Process Technology – Fully Static Operation • Power Consumption at 4 MHz, 3V, 25oC – Active: 3.4 mA – Idle Mode: 1.4 mA – Power Down Mode: <1 µA • I/O and Packages – 20 Programmable I/O Lines – 28-pin PDIP and 32-pin TQFP • Operating Voltage – 2.7V - 6.0V (IN90LS2333) – 4.0V - 6.0V (IN90S2333 ) • Speed Grades – 0 - 4 MHz (IN90LS2333 ) 0 - 8 MHz (IN90S2333 ) 2 IN90S2333DW, IN90LS2333DW, Block Diagram 3 IN90S2333DW, IN90LS2333DW, Pin Descriptions VCC Supply voltage GND Ground Port B (PB5..PB0) Port B is a 6-bit bi-directional I/O port with internal pullup 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 IN90S2333. The port B pins are tristated when a reset condition becomes active, even if the clock is not running. Port C (PC5..PC0) Port C is a 6-bit bi-directional I/O port with internal pullup 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 the analog inputs to the A/D Converter. The port C pins are tristated when a reset condition becomes active, even if the clock is not running. 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. Port D also serves the functions of various special features of the IN90S2333 The port D pins are tristated when a reset condition becomes active, even if the clock is not running. RESET Reset input. An external reset is generated by a low level on the RESET pin. Reset pulses longer than 50 ns will generate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2 Output from the inverting oscillator amplifier AVCC via a low-pass filter. See This is the supply voltage pin for the A/D Converter. It should be externally connected to VCC Datasheet for details on operation of the ADC. AREF This is the analog reference input for the A/D Converter. For ADC operations, a voltage in the range 2.7V to AVCC must be applied to this pin. 4 IN90S2333DW, IN90LS2333DW, AGND If the board has a separate analog ground plane, this pin should be connected to this ground plane. Otherwise, connect to GND. 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 Arithmetic Logic Unit (ALU) 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 Xregister, Y-register and Z-register. 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. 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. AVR IN90S2333 Architecture 5 IN90S2333DW, IN90LS2333DW, The I/O memory space contains 64 addresses for CPU peripheral functions as Control Registers, Timer/Counters, 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 Programmable Flash memory. With the relative jump and call instructions, the whole 1K/2K word address space is directly accessed. Most AVR instructions have a single 16-bit word format. Every program memory address contains a 16or 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 interrupts are executed). The 8-bit stack pointer SP is read/write accessible in the I/O space. The 128 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. Memory Map 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 the priority. 6 IN90S2333DW, IN90LS2333DW, Register Summary Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 $3F ($5F) SREG I T H S V N Z C $3E ($5E) Reserved - - - - - - - - $3D ($5D) SP SP7 SP6 SP5 SP4 SP3 SP2 SP1 SP0 - - - - - - $3C ($5C) Reserved $3B ($5B) GIMSK INT1 INT0 $3A ($5A) GIFR INTF1 INTF0 $39 ($59) TIMSK TOIE1 OCIE1 - - TICIE1 - TOIE0 - $38 ($58) TIFR TOV1 OCF1 - - ICF1 - TOV0 - $37 ($57) Reserved $36 ($56) Reserved $35 ($55) MCUCR - SE SM ISC11 ISC10 ISC01 ISC00 $34 ($54) MCUSR - - - - WDRF BORF EXTRF PORF $33 ($53) TCCR0 - - - - - CS02 CS01 CS00 $32 ($52) TCNT0 $31 ($51) Reserved $30 ($50) Reserved $2F ($4F) TCCR1A $2E ($4E) $2D ($4D) Timer/Counter0 (8 Bits) COM1 1 COM10 - - - - PWM11 PWM10 TCCR1B ICNC1 ICES1 - - CTC1 CS12 CS11 CS10 TCNT1H Timer/Counter1 - Counter Register High Byte $2C ($4C) TCNT1L Timer/Counter1 - Counter Register Low Byte $2B ($4B) OCR1H Timer/Counter1 - Output Compare Register High Byte $2A ($4A) OCR1L Timer/Counter1 - Output Compare Register Low Byte $29 ($49) Reserved $28 ($48) Reserved $27 ($47) ICR1H Timer/Counter1 - Input Capture Register High Byte $26 ($46) ICR1L Timer/Counter1 - Input Capture Register Low Byte $25 ($45) Reserved $24 ($44) Reserved $23 ($43) Reserved $22 ($42) Reserved $21 ($41) WDTCR $20 ($40) Reserved - - - WDTOE WDE WDP2 WDP1 WDP0 - - - EERIE EEMWE EEWE EERE PORTB0 $1F ($3F) Reserved $1E ($3E) EEAR EEPROM Address Register $1D ($3D) EEDR EEPROM Data Register $1C ($3C) EECR $1B ($3B) Reserved $1A ($3A) Reserved $19 ($39) Reserved - $18 ($38) PORTB - - PORTB5 PORTB4 PORTB3 PORTB2 PORTB1 $17 ($37) DDRB - - DDB5 DDB4 DDB3 DDB2 DDB1 DDB0 $16 ($36) PINB - - PINB5 PINB4 PINB3 PINB2 PINB1 PINB0 PORTC0 $15 ($35) PORTC - - PORTC5 PORTC4 PORTC3 PORTC2 PORTC1 $14 ($34) DDRC - - DDC5 DDC4 DDC3 DDC2 DDC1 DDC0 $13 ($33) PINC - - PINC5 PINC4 PINC3 PINC2 PINC1 PINC0 $12 ($32) PORTD PORT D7 PORTD6 PORTD5 PORTD4 PORTD3 PORTD2 PORTD1 PORTD0 $11 ($31) DDRD DDD7 DDD6 DDD5 DDD4 DDD3 DDD2 DDD1 DDD0 $10 ($30) PIND PIND7 PIND6 PIND5 PIND4 PIND3 PIND2 PIND1 PIND0 $0F ($2F) SPDR SPI Data Register $0E ($2E) SPSR SPIF WCOL - - - - - - $0D ($2D) SPCR SPIE SPE DORD MSTR CPOL CPHA SPR1 SPR0 $0C ($2C) UDR UART I/O Data Register 7 IN90S2333DW, IN90LS2333DW, Register Summary (Continued) Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 $0B ($2B) UCSRA RXC TXC UDRE FE OR - - Bit 0 - $0A ($2A) UCSRB RXCIE TXCIE UDRIE RXEN TXEN CHR9 RXB8 TXB8 $09 ($29) UBRR UART Baud Rate Register $08 ($28) ACSR ACD AINBG ACO ACI ACIE ACIC ACIS1 ACIS0 $07 ($27) ADMUX - ADCBG - - - MUX2 MUX1 MUX0 $06 ($26) ADCSR ADEN ADSC ADFR ADIF ADIE ADPS2 ADPS1 ADPS0 $05 ($25) ADCH - - - - - - ADC9 ADC8 $04 ($24) ADCL ADC7 ADC6 ADC5 ADC4 ADC3 ADC2 ADC1 ADC0 $03 ($23) UBRRHI $02 ($22) Reserved $01 ($21) Reserved $00 ($20) Reserved UART Baud Rate Register High 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 one 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.
