Additional features: Battery monitor and reset. CPU Supervisors DS1233 EconoResets provide complete power monitoring and power-on reset functions to improve system operation and protect nonvolatile memories. The DS1233D is compatible with processors that are capable of initiating a OsoftO reset output at the RST input. The DS1232LP and DS1832 extend the DS1233 functionality with a fully integrated watchdog to monitor processor operation and will restart a system when the P is no longer executing instructions. DS1834 is a complete 3 V and 5 V monitoring and power-on reset solution for mixed voltage systems.

Variations in the product family include 3 types of serial interfaces (1-Wire, 2-wire, and 3-wire), on-chip E2PROM memory (up to 256 bytes), multi-sense capability (up to ), and accuracy/price trade-offs. No external components are required to sense temperature and convert it to a digital word that can be read by a P. Because of the factory calibration, there is no need for the designer to perform any compensation or linearization over the operating range (55C to +125C). The nonvolatile thermostat trip points and dedicated thermostat outputs allow for standalone (no P required) thermostat operation. Applications include thermal management of personal computers and servers, office electronics, equipment racks, HVAC environmental control, and process monitoring/control. * The DS1232LP is a low power pin- and function-compatible replacement for the DS1232. Mfr.Os Type High-Speed Microcontrollers Dallas Semiconductor high-speed microcontrollers are revolutionary products in the 8051 microcontroller family which deliver up to 3 times the performance of industry standard 8051s just by dropping into an existing socket. This is accomplished by using 4 clocks per instruction instead of the usual 12, without changing crystal frequency. All parts are instruction set-compatible with the 80C51/87C51. Type DS80C320 is pin-for-pin compatible with 80C32, including the 3-volt version, type DS80C323. Type DS80C310 is a cost-reduced version of type DS80C320. Type DS87C520 is pin-forpin compatible with the 80C51/87C51, and includes 16 kB of EPROM, 1.2 kB of SRAM. Type DS87C530 contains the same features as type DS87C520, plus a real-time clock and 1 kB non-volatile SRAM. All of the high-speed controllers, except type DS80C310, include dual serial port, power-on reset, and watchdog timer. Mfr.Os Type No. of Pins Package Clock Speed Max.
