FAQ

What core does it use?

The device uses a 16-bit RISC core with a 16-register file. This architecture reduces code size and increases arithmetic throughput versus many 8-bit alternatives, making it suitable for control and signal tasks.

What supply voltage is required?

Supply operation is within the 1.8?C3.6 V window. This allows direct use with standard single-cell lithium or multiple alkaline configurations, reducing the need for intermediate regulation in many designs.

How many I/O pins are available?

The package exposes 16 general-purpose I/O pins. These pins support peripheral functions such as timers and comparator inputs to minimize external components in compact systems.

Does it support low-power modes?

Yes. The device implements five low-power modes (LPM0?CLPM4). Designers can trade off active performance for minimal standby current to maximize battery life in intermittent-activity applications.

What package options exist?

This part is supplied in a 20-pin TSSOP (IRSAR) package. The small form factor simplifies PCB routing and fits constrained layouts common in handheld and embedded modules.
