prescaler

[′prē‚skāl·ər]
(electronics)
A scaler that extends the upper frequency limit of a counter by dividing the input frequency by a precise amount, generally 10 or 100.

Attiny13 also contains an 8 bits timer with a prescaler. In order to configure the timer we need to set 3 registers: TCCR0A, TCCR0B, TCNT0, and TIMSK0.
It has a wide range of peripheral functions, including high-speed DMA, multi-channel SIO, programmable timer, PLL, prescaler along with additional functionality.
Timer Mode allows only the main clock, sub clock oscillations, time base timer or watch prescaler to work.

The analog block supports MOSFET gate driver output and multiple analog inputs from -12V to up to +12V with optional prescaler. Pricing starts below $5 each in 250K quantities.
The classic feedback oscillator lends itself to meeting these requirements, (1) while an MMIC-based implementation results in a low cost solution incorporating ancillary circuits such as buffer amplifiers, a prescaler and a frequency doubler.
