GENERAL DESCRIPTION
ADuC7026 fully integrated, 1MSPS, 12-bit data acquisition system incorporating high performance multichannel ADC, 16/32-bit Flash/EE Memory single chip. consists single-ended inputs. additional inputs available multiplexed with output pins. operate single-ended differential input modes. input voltage VREF. drift bandgap reference, temperature sensor voltage comparator complete peripheral set. part also integrates buffered voltage output DACs onchip. output range programmable three voltage ranges. device operates from on-chip oscillator generating internal high-frequency clock MHz. This clock routed through programmable clock divider from which core clock operating frequency generated. microcontroller core ARM7TDMI, 16/32-bit RISC machine, offering MIPS peak performance. Bytes non-volatile Flash/EE provided on-chip well Bytes SRAM. Both Flash/EE SRAM memory arrays mapped into single linear array. On-chip factory firmware supports in-circuit serial download UART JTAG serial interface ports while nonintrusive emulation also supported JTAG interface. These features incorporated into low-cost QuickStart Development System supporting this MicroConverter family. parts operate from 2.7V 3.6V specified over industrial temperature range -40°C 85°C. When operating 45MHz power dissipation 300mW. ADuC7026 available 80-lead LQFP package.
compressed into 16-bits, Thumb instruction set. Faster execution from 16-bit memory greater code density usually achieved using Thumb instruction instead instruction set, which makes ARM7TDMI core particularly suitable embedded applications. However Thumb mode limitations: Thumb code usually uses more instructions same job, code usually best maximising performance time-critical code. Thumb instruction does include some instructions that needed exception handling, code needs used exception handling. ARM7TDMI User Guide details core architecture, programming model both Thumb instruction sets.
Long multiple
ARM7TDMI instruction includes four extra instructions which perform 32-bit 32-bit multiplication with 64-bit result 32-bit 32-bit multiplication-accumulation (MAC) with 64-bit result.
EmbeddedICE
EmbeddedICE provides integrated on-chip support core. EmbeddedICE module contains breakpoint watchpoint registers which allow code halted debugging purposes. These registers controlled through JTAG test port. When breakpoint watchpoint encountered, processor halts enters debug state. Once debug state, processor registers inspected well Flash/EE, SRAM Memory Mapped Registers.

ARM7TDMI ARM7 core with additional features: support Thumb bit) instruction set. support debug support long multiplies include EmbeddedICE module support embedded system debugging.
Exceptions
supports five types exceptions, privileged processing mode each type. five type exceptions are: Normal interrupt IRQ. provided service generalpurpose interrupt handling internal external events Fast interrupt FIQ. provided service data transfer communication channel with latency. priority over Memory abort Attempted execution undefined instruction Software interrupt (SWI) instruction which used make call operating system. Typically programmer will define interrupts higher priority interrupt, i.e. faster response time, programmer define interrupt FIQ.

Registers
ARM7TDMI total registers, which general purpose registers status registers. Each operating mode dedicated banked registers. When writing user-level programs, general purpose 32-bit registers r14), program counter (r15) current program status register (CPSR) usable. remaining registers used only system-level programming exception handling. When exception occurs, some standard register replaced with registers specific exception mode. exception modes have replacement banked registers stack pointer (r13) link register (r14) represented Figure fast interrupt mode more registers fast interrupt processing, that interrupt processing begin without need save restore these registers thus save critical time interrupt handling process.

Note that ARM7TDMI will always (32-bit) mode when privileged modes, i.e. when executing interrupt service routines.
