ADUC7028Precision Analog Microcontroller, 12-Bit Analog I/O, ARM7TDMI®MCU | Integrated Circuits (ICs) | 2 | Active | TheADuC7019/ADuC7020/ADuC7021/ADuC7022/ADuC7024/ADuC7025/ADuC7026/ADuC7027/ ADuC7028 /ADuC7029are fully integrated, 1 MSPS, 12-bit data acquisition systems incorporating high performance multichannel ADCs, 16-bit/32-bit MCUs, and Flash®/EE memory on a single chip.The ADC consists of up to 12 single-ended inputs. An additional four inputs are available but are multiplexed with the four DAC output pins. The four DAC outputs are available only on certain models (ADuC7020, ADuC7026, ADuC7028, and ADuC7029). However, in many cases where the DAC outputs are not present, these pins can still be used as additional ADC inputs, giving a maximum of 16 ADC input channels. The ADC can operate in single-ended or differential input mode. The ADC input voltage is 0 V to VREF. A low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set.Depending on the part model, up to four buffered voltage output DACs are available on-chip. The DAC output range is programmable to one of three voltage ranges.The devices operate from an on-chip oscillator and a PLL generating an internal high frequency clock of 41.78 MHz (UCLK). This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an ARM7TDMI®, 16-bit/32-bit RISC machine, which offers up to 41 MIPS peak performance. Eight kilobytes of SRAM and 62 kilobytes of nonvolatile Flash/EE memory are provided on-chip. The ARM7TDMI core views all memory and registers as a single linear array.On-chip factory firmware supports in-circuit serial download via the UART or I2 C serial interface port; nonintrusive emulation is also supported via the JTAG interface. These features are incorporated into a low cost QuickStart™ development system supporting this MicroConverter®family.The parts operate from 2.7 V to 3.6 V and are specified over an industrial temperature range of −40°C to +125°C. When operating at 41.78 MHz, the power dissipation is typically 120 mW. The ADuC7019/ADuC7020/ADuC7021/ADuC7022/ADuC7024/ADuC7025/ADuC7026/ADuC7027/ADuC7028/ADuC7029 are available in a variety of memory models and packages (see Ordering Guide).APPLICATIONSIndustrial control and automation systemsSmart sensors, precision instrumentationBase station systems, optical networking |

ADUC7120Precision Analog Microcontroller, 12-Bit Analog Input/Output, ARM7TDMI MCU | Integrated Circuits (ICs) | 3 | Active | The ADuC7120/ADuC7121are fully integrated, 12-bit, 1 MSPS, data acquisition systems incorporating a high performance multichannel ADC, 16-bit/32-bit microcontroller unit (MCU), and Flash®/EE memory on a single chip.The analog-to-digital converter (ADC) consists of eleven single-ended inputs for the ADuC7120 (seven single-ended inputs for the ADuC7121) and two extra differential input pairs. The two differential input pairs can be routed through a programmable gain amplifier (PGA). The ADC can operate in single-ended or differential input mode. The ADC input voltage is 0 V to VREF. A low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set.The ADuC7120/ADuC7121 provide five current output digital-to-analog converters (DACs). The current sources (five current DACs) feature low noise and low drift, high-side current output at an 11-bit resolution. The five current digital-to-analog converters (IDACs) are as follows: IDAC0 with 250 mA full-scale (FS) output, IDAC1 with 200 mA FS output, IDAC2 with 45 mA FS output, IDAC3 with 80 mA FS output, and IDAC4 with 20 mA FS output.The ADuC7120/ADuC7121 also contain up to 12 voltage output DACs. The DAC output range is programmable to one of three voltage ranges.The devices operate from an on-chip oscillator and a phase-locked loop (PLL) generating an internal high frequency clock of 41.78 MHz (UCLK). This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an ARM7TDMI®, 16-bit/32-bit reduced instruction set computer (RISC) machine, which offers up to 41 MIPS peak performance. 8 kB of SRAM and 126 kB of nonvolatile Flash/EE memory are provided on chip. The ARM7TDMI core views all memory and registers as a single linear array.On-chip factory firmware supports in circuit serial download via the I2C serial interface port; nonintrusive emulation is also supported via the JTAG interface. These features are incorporated into a low costQuickStartdevelopment system supporting this MicroConverter®family.The devices operate from 3.0 V to 3.6 V, and they are specified over the −40°C to +105°C industrial temperature range. The IDACs are powered from a separate input power supply, PVDD. When operating at 41.78 MHz, the power dissipation is typically 120 mW. The ADuC7120/ADuC7121 are available in a 108-ball chip-scale package ball grid array [CSP_BGA].ApplicationsOptical modules—tunable laser |
