8-bit MCUs tout new embedded peripherals
8 February 2006
DSP, Micros & Memory
STMicroelectronics has expanded its ST7Lite family of 8-bit microcontrollers for power applications in lighting, low-end motor control, uninterruptible power supplies and ovens. The ST7FLit1xB series offers a choice of 16 and 20-pin packages, 2 KB or 4 KB of flash memory, and new embedded peripherals to bring added functionality to a range of cost-sensitive applications. There is also an enhanced 12-bit auto-reload timer, fast analog comparator with 16 internal voltage references, and other features.
The devices should be of particular interest for lighting applications, including fluorescent, high intensity discharge, LED control, and for LCD backlight management. Other uses such as low-end motor control, Transition Mode power factor correction, UPS, ovens and induction cookers will benefit from the range of advanced embedded peripherals in these devices, enabling applications to be smaller and costs to be lower.
The 12-bit timer in the new series includes four independent PWM output channels with programmable dead time generation, intended for use in half-bridge driving mode in lighting and motor control applications where PWM signals must not be allowed to overlap. The new comparator provides 16 selectable voltage references, and alongside the 10-bit ADC with op-amp, which is available across the ST7Lite family, makes the new series a cost-effective solution for many power applications. Other new features are a 32 MHz PLL and enhanced one-pulse mode functionality to allow more flexibility in the use of the peripherals.
Twenty-four variants offer different combinations of 2 KB or 4 KB of flash memory, either 128 bytes of data EEPROM or no EEPROM, and a 16-pin or 20-pin SO, DIP or QFN package, allowing the designer to make the optimum choice of MCU to meet the price, performance and size requirements of the application.
