Integrated chipsets for automotive CD systems
Toshiba Electronics has introduced two surface-mount chipsets that greatly simplify the task of designing compact disc (CD) modules for vehicle audio applications.
Toshiba's new home appliance microcontroller is based on the company's TLCS-870/C 16MHz 8-bit CPU core.
This core features 731 basic instructions and supports power conservation through a dual clock feature that allows the device to operate at 32.768kHz.
The core has been combined with 60Kbytes of SuperFlash low-cost, highly reliable flash memory, 2Kbytes of RAM, and a level of peripheral and interface capability that would not typically be found in a low-cost 64-pin device.
As a result, home appliance designers can use the microcontroller to implement key functions without the need for external components or additional circuit layout.
In addition to standard 8-bit, 16-bit, and watchdog timers, on-board peripherals include a 16-bit timer/counter capable of PWM output, and a high-resolution 16-channel 10-bit successive approximation type ADC.
The ADC can be used to process a variety of front panel and system analogue inputs.
Five serial interfaces offer UART, HSIO, and I2C connectivity, while giving the designer the flexibility to implement parallel communications as necessary.
Toshiba's SuperFlash implementation can be programmed much faster than many alternative flash technologies, allowing designers to program the microcontroller's on-board 60Kbytes in less than five seconds.
As well as offering enough memory to, in most cases, eliminate the need for external memory, the on-board flash provides a high level of pre- and post-production flexibility.
This flexibility comes from the availability of three distinct programming modes, namely parallel mode, serial PROM mode, and ISP (in system programming) mode.
The latter allows upgrades and fixes in the field under control of the user program, removing the need to switch off the output to an LCD panel or active output controls.
The TMP86FS49 is supplied in a P-QFP64 package.
