ISP solution. The ZPSD813F MCU support IC adds external flash
memory and programmable logic to 5-volt, 8-bit CISC designs without appreciably increasing
the power drain. For example, a second 32 Kb flash memory to enable concurrent ISP and a
CPLD to a 5-volt system with a 4MHz MCU clock will increase the power drain by 30.7mA.
Using this product to add the same functionality will increase the power drain by only
3.7mA. WSI Inc, 47280 Kato Rd, Fremont, CA 94538. 510-656-5400. Circle

Microcontroller. This Arithmetic Controller Engine (ACE) is a
microcontroller optimized for low power packaged in an 8-bit TSSOP. The ACE 1101
microcontroller features re-programmable EEPROM, a 16-bit multifunction timer, an internal
oscillator, and internal reset. The ACE 1101 is ideal for low power/battery-powered
applications such as wireless designs, consumer products and automotive systems. Fairchild
Semiconductor, 333 Western Ave, South Portland, Maine 04106.888-522-5372. 
Resistor networks. This manufacturer offers a wide variety of
custom resistor networks, resistor/capacitor networks and resistor/diode networks. This
product is a custom resistor/diode network. It allows the engineer to minimize space and
to obtain accurate resistor values. This product uses thick film hybrid technology.
Resistors are printed on the ceramic substrate and are trimmed to precise values of one
half of a percent. Sunrise Tek, 1308 Adams, Kansas City, KS 66103.

Crystal oscillator. The MTXL25 is a temperature compensated
crystal oscillator (TCXO) that is available with frequency stabilities of ±1.5ppm over
-20° to 70°C, ±2.5ppm over -30° to 75°C, and ±5ppm over -40° to 85°C operating
temperature. Frequency adjustment is by means of an internal trimmer. Output is HCMOS/TTL
compatible. Frequencies in the 9.6 to 32 MHz range are available. 5.0V and 3.0V options
are offered with voltage tuning. M-Tron Industries, PO Box 630, 100 Douglas
Ave, Yankton, SD 57078. 800-762-8800. Circle 656.
Pulse generators. The PCL240 line of programmable single-chip
high-speed pulse generators are CMOS LSIs. Each LSI oscillates high-frequency pulses to
drive the stepping motor and pulse train input servo motor according to the command
written through the CPU bus interface. The maximum output frequency is up to 2.4 Mpps. Nippon
Pulse Motor Co, No. 16-13, 2-Chome, Hongo, Bunkyo-Ku, Tokyo 113-0033, Japan.
