TOSHIBA EXPANDS ITS 4-BIT MICROCONTROLLER FAMILY WITH A LOW-COST, LOW-VOLTAGE VERSION.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Sept. 17, 1996--Toshiba America Electronic Components, Inc. (TAEC TAEC Toshiba America Electronic Components, Inc. TAEC Thailand Atomic Energy Commission ) today announced an addition to its TLCS-47E 4-bit microcontroller family that also features low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains operation and low power dissipation. This new member of the TLCS-47E microcontroller line further expands Toshiba's 4-bit offering to meet a wide variety of applications and specific customer requirements. "This new 4-bit microcontroller offers many features in a low-cost device," said Scott Gaw, product marketing engineer for TAEC's microcomputer products. "Besides complementing an already extensive line of 4-bit microcontrollers, the TMP TMP (thymidine monophosphate): see thymine. 47x206 can operate at low voltage, features low voltage detection and zero cross detectors, and has two channels of 12-bit timers/counters." The new device is targeted towards consumer electronics, appliance control, industrial and hand-held electronics applications, and is available in either a mask ROM or OTP (1) (One Time Programmable) Refers to programming content or logic into chips such as EPROMs and EEPROMs, which cannot be reversed. See antifuse. (2) (One Time P version containing either 2 kilobytes (KB) of ROM or 2KB of EPROM EPROM in full erasable programmable read-only memory Form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused. (OTP versions). The device comes in a 20-pin SOP or 20-pin DIP package. The TMP47x206 can operate at a voltage range from 2.2 volts (V) to 5.7V. Low voltage operation is a distinct advantage for portable devices that work from batteries. The on-chip programmable low-voltage detector (LVD See LVDS. LVD - Low Voltage Differential ) controls threshold voltage by a register and allows the circuit to operate intermittently to save power. When the LVD detects AC power loss in a system equipped with battery or capacitor backup, it switches the circuitry to a battery backup, puts the microcontroller into the hold mode to reduce power consumption, and can operate intermittently to further reduce power consumption. In addition, the LVD itself is not power hungry. Current consumption is only 100 microamperes while covering a wide voltage detection range of 2.7 to 4.05V. The TMP47x206 also features a zero cross detector function that can be used for commercial power supply frequency input and time base or triac control. This feature allows users to generate a clock reference from AC power and to detect AC power loss. The zero cross detector has a zero cross accuracy of 90 microseconds (max), with hold release and interrupts that can occur at rising and falling edges. The interrupt priority is software selectable. Toshiba's new microcontroller also has five high current outputs with LED direct drive capability or triac direct control with a typical output of 20 milliamperes (mA). This reduces the need and cost of additional external drivers or other high current output drivers. It also simplifies the system design by reducing external components. In addition, the TMP47x206 device offers pulse and reset outputs. The pulse output contains a buzzer drive/carrier for remote control options. The new device has two channels of 12-bit timers/counters that can be used as event counters, programmable timers, or pulse width pulse width Pulse duration Cardiac pacing The duration of a pacing pulse in msecs measurement. It also contains a watchdog timer that quickly detects central processing unit See CPU.
