TOSHIBA

Toshiba Electronics Europe (TEE) has launched a high-performance, 32-Bit microcontroller that will simplify the addition of USB and SD card connectivity to audio equipment such as car radios and a variety of other applications requiring USB connectivity.

The TMP92FD28FG incorporates an on-board USB 2.0 controller, 512KBytes of Flash memory, 32KBytes of internal RAM and extensive serial connectivity options. As a result, the device provides a singlechip solution for both host processing and connectivity control in audio applications such as car radios and other high-performance designs where USB interfaces are an important requirement.

Operating at speeds up to 20MHz, the TMP92FD28FG is based on TOSHIBA’s TLCS-900/H1 32-Bit CPU core, which combines RISC-level performance with the benefits of a CISC architecture. The on-board USB 2.0 controller offers full-speed 12MBit/s operation. Additional connectivity includes a UART/SPI controller that supports SPI communication with SD and MMC memory cards, a high-speed serial interface offering speeds up to 10MBit/s, I2C interfaces, and an IrDA version 1.0 interface.

In addition to its comprehensive on-board connectivity options, the TMP92FD28FG also features a memory controller and interrupt controller. Timer functionality comprises a real time clock timer, a watchdog timer, an 8-bit timer (six-channel) and a 16-Bit timer (twochannel). The new microcontroller’s TLCS-900/H1 core operates at up to 20MHz for minimum instruction execution times of 50ns and allows designers to expand external memory up to 16MBytes of linear address space.

Forty-seven interrupts can be accommodated, while three HALT modes and a ‘key on wakeup’ facility minimise power consumption during standby mode. The TMP92FD28FG is available in a choice of two compact 100-pin QFP packages with respective dimensions of 14mm x 14mm and 14mm x 20mm. Operating voltage is from 3.0V to 3.6V for external I/O and 1.4V to 1.6V internally.
