The HCTL-1101-PLC is a CMOS bipolar stepper motor driver and high-speed quadrature decoder manufactured by Broadcom Limited. It features a parallel interface control designed for precision motion sensing and industrial applications. The component operates within a temperature range of -20°C to +85°C and utilizes a PLCC package. It is classified under Motor / Motion / Ignition Controllers & Drivers.
This component has been officially declared obsolete by Broadcom Limited. Availability is restricted to existing stock or secondary market sources. Verify authenticity and condition carefully when sourcing from non-direct suppliers, as original manufacturing support is discontinued.
Select this part only if legacy compatibility with parallel interface controllers is required. Consider modern alternatives for new designs due to obsolescence. Ensure the PLCC package footprint matches the target PCB layout constraints before procurement.
Part of the HCTL series of motion control ICs from Broadcom/Avago. Specifically designed for integrating encoder feedback and motor driving functions in compact form factors suitable for embedded motion control solutions.
HCTL-2017-PLC is listed as a related interface component, though classification differs. No direct pin-compatible substitute is confirmed in public documentation. Evaluate functional equivalents for new designs.
