The W27E520 is a 64k×8 bit electrically erasable EPROM device with high speed and low power consumption. It has internal latches for the lower 8 address lines to multiplex with the 8 data lines, which can save external TTL components, reduce cost and space. In normal read mode, it only needs one power supply within the range of 4.5V to 5.5V. The W27E520 also provides an electrical chip erase function, which is very convenient for changing/updating the contents in the device.

The W27E010 128K × 8 ELECTRICALLY ERASABLE EPROM is a high speed, low power Electrically Erasable and Programmable Read Only Memory organized as 131072 × 8 bits that operates on a single 5 volt power supply.

This document describes the features and characteristics of WINBOND LPC I/O W83697HF.

The W91473 series are Si-gate CMOS IC tone/pulse switchable dialers containing a 14-channel automatic dialing memory, including a 16-digit × 3 emergency dialing memory and a 16-digit × 10 channel repertory memory that provides a 32-digit mercury memory. These dialers also provide flash, clear, hold, lock, and one-key redial functions.

The W39L040 is a 4Mbit, 3.3-volt only CMOS flash memory organized as 512K×8 bits. For flexible erase capability, the 4Mbits of data are divided into 8 uniform sectors of 64 Kbytes, which are composed of 16 smaller even pages with 4 Kbytes. The byte-wide (× 8) data appears on DQ7 − DQ0. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is not required. The unique cell architecture of the W39L040 results in fast program/erase operations with extremely low current consumption (compared to other comparable 3.3-volt flash memory products). The device can also be programmed and erased by using standard EPROM programmers.

The W24129A is a high-speed, low-power CMOS static RAM organized as 16384 × 8 bits that operates on a single 5-volt power supply. This device is manufactured using Winbond's high performance CMOS technology. Features include high-speed access time, low-power consumption, fully static operation, inputs and outputs directly TTL compatible, three-state outputs.

W27C4096 is a high speed, low power electrically erasable and programmable read only memory organized as 262144 × 16 bits that operates on a single 5 volt power supply. The W27C4096 provides an electrical chip erase function.

W78E58 is an 8-bit microcontroller that is functionally compatible with W78C58, except that the mask ROM is replaced by a flash EEPROM with a size of 32 KB. To facilitate programming and verification, the flash EEPROM inside the W78E58 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E58 microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the market. It is functionally compatible with the industry-standard 80C52 microcontroller series, except that one extra 4-bit bit-addressable I/O port(Port 4) and two additional external interrupts (INT2 , INT3 ). The W78E58 contains four 8-bit bi-directional and bit-addressable I/O ports, three 16-bit timer/counters, and a serial port. These peripherals are supported by a eight-source, two-level interrupt capability. There are 256 bytes of RAM and an 32 KB flash EEPROM for application programs. The W78E58 microcontroller has two power reduction modes, idle mode and power-down mode, both of which are software selectable. The idle mode turns off the processor clock but allows for continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power consumption. The external clock can be stopped at any time and in any state without affecting the processor.

The W78E54B 8-bit microcontroller is 8051 compatible and has low power consumption and a wider frequency range.

The W78E54 is an 8-bit microcontroller that is functionally compatible with the W78C54, except that the mask ROM is replaced by a flash EEPROM with a size of 16 KB. To facilitate programming and verification, the flash EEPROM inside the W78E54 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E54 microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the market. It is functionally compatible with the industry-standard 80C52 microcontroller series, except that one extra 4-bit bit-addressable I/O port (Port 4) and two additional external interrupts (INT2 , INT3 ). The W78E54 contains four 8-bit bidirectional and bit-addressable I/O ports, three 16-bit timer/counters, and a serial port.

The external clock can be stopped at any time and in any state without affecting the processor.

W78E51C is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W78E51C is fully compatible with the standard 8051. The W78E51C contains many enhanced functions, such as new defined peripheral, reduced EMI emission, more flexible lock and MOVC inhibit, higher security and faster clock speed.
