MAXIM Manuals

This file describes situations where MAXQ1010 revision A1 components perform differently than expected or differently than described in the data sheet.

This document is an errata sheet for MAXQ622 revision B1 components, describing the abnormal behaviors of these components in certain situations. The errata sheet provides workarounds. The main issues include the watchdog timer reset locking the IC in reset and flash program/erase operations failing in clock-divided mode.

The DS4077 is an integrated voltage-controlled crystal oscillator (VCXO) module designed to provide reference clock generation in base stations, telecom/datacom, and wireless applications. It features low jitter and low phase noise.

TINI® Power SoCs analog integration technology provides space for new functions in mobile platforms. It combines power and system functions into a single chip to save board space, reduce the bill of materials, and improve performance. It also integrates a microcontroller and memory to offload the applications processor and allow one design to be ported across multiple platforms. Additionally, it extends battery life and reduces heat with highly efficient power-management functions. The technology leverages a broad portfolio of high-performance building blocks, including advanced IP cores like ModelGauge™, FlexSound®, and TacTouch®.

The MAX705-MAX708/MAX813L are microprocessor (µP) supervisory circuits that reduce the complexity and number of components required to monitor power-supply and battery functions in µP systems. These devices significantly improve system reliability and accuracy com- pared to separate ICs or discrete components. The MAX705/MAX706/MAX813L provide four functions: 1) A reset output during power-up, power-down, and brownout conditions. 2) An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6 seconds. 3) A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power sup- ply other than +5V. 4) An active-low manual-reset input. The MAX707/MAX708 are the same as the MAX705/ MAX706, except an active-high reset is substituted for the watchdog timer. Th

The DS80C320/DS80C323 series are high-performance, low-power 8051-compatible microcontrollers that are available in 40-Pin DIP, 44-Pin PLCC, and 44-Pin TQFP packages.

The DS4125–DS4776 DS4-XO series crystal oscillators are from Maxim company, offer frequencies at 125MHz, 155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz, 622.08MHz and 77.76MHz, and have very low jitter and phase noise. They are suitable for systems with tight tolerances. The package size is 5.0mm x 3.2mm x 1.49mm and the package type is 10-pin LCCC surface mount ceramic.

MAX1044/ICL7660 is a monolithic CMOS switched-capacitor voltage converter that inverts, doubles, divides, or multiplies a positive input voltage. It is pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with no external diode over the full temperature range. It delivers 10mA with a 0.5V output drop. The MAX1044 has a BOOST pin that raises the oscillator frequency above the audio band and reduces external capacitor size requirements. The MAX1044/ICL7660 combine low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. Applications include generating a -5V supply from a +5V logic supply to power analog circuitry. For applications requiring more power, the MAX660 delivers up to 100mA with a voltage drop of less than 0.65V.

The MAX4200–MAX4205 are ultra-high-speed, open-loop buffers featuring high slew rate, high output current, low noise, and excellent capacitive-load-driving capability. They use a proprietary architecture to achieve up to 780MHz -3dB bandwidth, 280MHz 0.1dB gain flatness, 4200V/µs slew rate, and ±90mA output current drive capability. They are suitable for driving high-speed analog-to-digital converter (ADC) inputs or for data-communications applications.

MAX690A/MAX692A/MAX802L/MAX802M/MAX805L Supervisory Circuits, reduce the complexity and number of components required for power-supply monitoring and battery-control functions in microprocessor (µP) systems

This datasheet provides details of Maxim DG508A/DG509A, including applications, features, etc.

The DS89C430 and DS89C450 are the highest performance available in 8051-compatible microcontrollers. They feature newly designed processor cores that execute instructions up to 12 times faster than the original 8051 at the same crystal speed. Typical applications will experience a speed improvement up to 10x.

The MAX793/MAX794/MAX795 microprocessor (µP) supervisory circuits monitor and control the activities of +3.0V/+3.3V µPs by providing backup-battery switchover, among other features such as low-line indication, µP reset, write protection for CMOS RAM, and a watchdog. The backup-battery voltage can exceed VCC, permitting the use of 3.6V lithium batteries in systems using 3.0V to 3.3V for VCC. The MAX793/MAX795 offer a choice of reset threshold voltage range. The MAX794’s reset threshold is set externally with a resistor divider.

The MAX202E-MAX213E/MAX232E/MAX241E line drivers/receivers are designed for RS-232 and V.28 communications
