The DS5001FP 128k Soft Microprocessor Chip is an 8051-compatible Secure Microcontroller family, which is based on nonvolatile RAM rather than ROM.Dallas' 'soft' microprocessors can be programmed after installation in a system, which facilitates frequent software upgrades, adaptive programs, customized systems, etc. The user-set program and data partitions can also be modified to optimize reprogramming.Dallas' nonvolatile CMOS technology sets the standard for low-power consumption. With a user-supplied lithium battery, the on-chip power management circuitry can maintain all nonvolatile resources for greater than 10 years in the absence of external power.DS5001FP also provides crashproof operation in portable systems by saving the operating state and providing a power-fail reset, power-fail interrupt, and watchdog timer.The DS5001FP is intended for applications requiring large memory addressing. It includes bank switching that, with a little extra logic, enable it to address 252kbytes of data memory. The DS5001FP is available in a module that includes the RAM, a lithium cell and real-time clock (see the DS2251).The DS5001FP is ideal for data logging applications that require large, nonvolatile memory storage. It easily connects to a Dallas real-time clock to add nonvolatile, time-stamped data entry. Note: Designers must have the following documents to fully use all the features of this device.

The MAXQ7667 smart system-on-a-chip (SoC) provides a time-of-flight ultrasonic distance-measuring solution. The device is optimized for applications involving large distance measurement with weak input signals or multiple target identification. The MAXQ7667 features high signal-to-noise ratio achieved by combining flexible electronics with the intelligence necessary to optimize each function as environmental and target conditions change.An integrated burst signal generator and echo reception components process ultrasonic signals between 25kHz and 100kHz. Echo reception components include a programmable gain low-noise amplifier (LNA), a 16-bit sigma-delta ADC to digitize the received echo signals, and digital signal processing (DSP). DSP limits noise with a bandpass filter, and creates an echo envelope through demodulation and lowpass filtering. Input referred noise is a low 0.7µVRMS. A programmable phase-locked loop (PLL) frequency synthesizer supplies the reference frequency for the burst generator and the clock for the echo receiver's digital filter. An embedded 16-bit MAXQ20 microcontroller (µC) controls all the preceding functions.The µC optimizes the burst frequency and reception frequency for each transmission at any temperature. The MAXQ7667 achieves smart sensing by monitoring the echo signals and then actively changing the transmitted and received parameters to obtain optimum results. Digital filtering and burst synthesis do not require CPU intervention. This leaves all the CPU power available for echo optimization, communication, diagnostics, and additional signal processing.The MAXQ7667 operates with three different power supply voltages: +5V, +3.3V, and +2.5V. Two internal linear regulators allow operation from a single +5V supply when three external power supplies are not available. Alternatively, the MAXQ7667 can control an external pass transistor to allow operation from a single supply voltage of +8V to +65V or more, depending on the external component tolerance. The device is available in a 48-pin LQFP package and is specified to operate from -40°C to +125°C. Note: Designers must have the following documents to fully use all the features of this device. This data sheet contains pin descriptions, feature overviews, and electrical specifications. Errata sheets contain deviations from published specifications.
