STMicroelectronics has expanded its ST7Lite series of 8-bit Flash microcontrollers with the introduction of the ST7FLite1 and ST7FLite2 that carry 4KB and 8KB of Flash memory, respectively, in 20-pin packages.

Both embedded MCUs provide software-configurable x4 and x8 PLLs, an embedded op amp with a 13-bit resolution in the 0 to 430mV range, an advanced auto-reload timer with simultaneous four-channel PWM generation, and a single input capture at up to 32MHz providing high PWM resolution.

In addition to the Flash program memory, which includes in-application programming, readout and write protection capability, the ST7Lite series features a 1MHz RC oscillator, reset circuitry with LVD, as well as a 7-channel 10-bit ADC with 3.5?s conversion time.

The choice of power consumption to processing power ratio is also available via software control through five low power modes, including 1?A in HALT mode and 'Auto Wake Up From HALT' mode with 15?A consumption. Additional features of the series include a range of pin-to-pin compatible devices, with and without E2 data and with external oscillator capabilities.

The devices employ proprietary Extended Flash technology, which provides individual byte programming capability and operates as standard from 2.4V to 5.5V.

The ST7Lite family is isuited to a wide range of applications including appliances, alarms, sensors, toys, battery-supplied equipment, and industrial control.
