CD4541B programmable timer consists of a 16-stage binary counter, an oscillator that is controlled by external R-C components (2 resistors and a capacitor), an automatic power-on reset circuit, and output control logic. The counter increments on positive-edge clock transitions and can also be reset via the MASTER RESET input.
1. Low Symmetrical Output Resistance, Typically 100Ω at VDD = 15V 2. Built-In Low-Power RC Oscillator 3. Oscillator Frequency Range : DC to 100kHz 4. External Clock (Applied to Pin 3) can be Used Instead of Oscillator 5. Operates as 2N Frequency Divider or as a Single-Transition Timer 6. Q/Q Select Provides Output Logic Level Flexibility 7. AUTO or MASTER RESET Disables Oscillator During Reset to Reduce Power Dissipation 8. Operates With Very Slow Clock Rise and Fall Times

The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.
