Nonvolatile SRAMs
These Dallas Semiconductor Nonvolatile Static RAMs integrate a lithium power source and intelligent control circuitry to
retain data even in the absence of system power. Nonvolatile SRAMs feature unlimited write endurance and read/write
access times as fast as 70 ns. DIP package devices have a 0.600" row spacing, 0.100" pin spacing and JEDEC pinouts.
PowerCap Modules (PCM) are surface-mount devices that feature a two-piece construction with the DS9034PC

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 ÒsoftÓ 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 µP is no longer executing instructions. DS1834 is a
complete 3 V and 5 V monitoring and power-on reset solution for mixed voltage systems.

Devices
The core feature set of this family of temperature sensors is a direct-to-digital readout of the temperature ( ³9 bits), over-
and under-temperature nonvolatile thermostat set points, factory-calibration, and dedicated thermostat logic outputs.
Variations in the product family include 3 types of serial interfaces (1-Wire
ª
, 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 µP. Because of the factory calibration,
there is no need for the designer to perform any compensation or linearization over the operating range (Ð55¡C to
+125¡C). The nonvolatile thermostat trip points and dedicated thermostat outputs allow for standalone (no µP 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.
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-for-
pin 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.
