Winbond has launched highly integrated general-purpose SoCs in combination with a comprehensive development suite. W90P710 and W90N745 promise to shorten the time required for system vendors to develop products and help them reduce time-to-market. For these new devices, Winbond uses the high-performance 32bit ARM7TDMI core from ARM Ltd and integrates it with a built-in Ethernet MAC.

The new devices also include a USB2.0 full speed Host/Device Controller enabling applications to connect to computer peripherals through the USB interface, enhancing the product's overall added-value.

W90P710/W90N745 use the ARM7TDMI microprocessor core manufactured using a 0.18?m process. During normal operations it can reach frequencies of 80MHz, while the 176Pin/128-Pin LQPF packaging provides improved power conservation and lower cost. The W90P710/W90N745 come with a 4Kbyte cache. These can also be set by product developers to serve as on-chip RAM if necessary.

The new chips incorporate a flexible External Bus Interface that allows direct access I/O components such as ROM, Flash, SDRAM and PCMCIA Card. W90P710 provides for screen displays a high-definition TFT/STN LCD controller. Apart from USB and EBI, W90P710/W90N745 also provide four UART interfaces that customers can design to connect to more equipment such as a bar-code scanner, VFD module, debug port and Bluetooth module.

In terms of system integration, apart from point-of-sale applications, W90P710 is also suitable for data collectors, electronic picture frames or other products that use LCD displays. W90N745, on the other hand, is suited to network applications such as management switch, IP camera, VoIP and printer servers.

8bit SoC series
Apart from the 32bit SoC, Winbond is also releasing the 8bit LPC MCU W79E82x series, which includes W79E825, W79E824, W79E823, W79E822 and W79E821. This series is designed for MCUs that require a small package, little I/O and small Flash memory capacity. These are suited to standard industrial products such as UPS, power supply control, charger and access security. Customers are now placing samples of this design solution.

The advantage of the series is its high processing speed as it can achieve up to 2.5 times the performance of the traditional 8051 at the same operating frequency, the company said. It can reach processing speeds up to 20MHz, with 1,000 to 16,000 of internal flash ROM and a small 20-pin packaging, making it suitable for different categories of products. It also incorporates the Watch Dog Timer, allowing different scheduling settings and a low-power voltage reset function.

The Winbond W79E82x series is also designed for products that require high noise immunity. Its internal protective circuitry has been reinforced to meet the requirement of working environments. PWM output is also provided to control motor RPM ensuring optimal wear. Apart from the above, the W79E82x series also offers a four-channel ADC for capturing external signals. The I/O pins are equipped with interrupts providing real-time processing response.

The product's development environment also includes the JTAG emulator, software development system, compiler and supporting documentation. This comprehensive development suite will help designers shorten product development cycles and entry into the market quickly. Choose the W79E82x series, its In Circuit Program (ICP) function can be used to update the system online through the compiler, improving its flexibility and expandability for customers.
