2 Understanding PCM6xx0-Q1 Hardware and Software Compatibility

Hardware Compatibility: The PCM6xx0-Q1 family is offered in the same ultra-small 5 mm × 5 mm QFN package. The pinout for PCM6xx0-Q1 devices are similar except that for the input pins to accommodate different channel and boost options. This allows easy and quick migration of hardware schematics and layout as the systems requirements change across projects and end-applications or evolve over time. The pin-compatibility diagram, as Figure 2-1 shows, highlights the minor re-definition in pinout between PCM6xx0-Q1 products to enable additional features.

For example, the only hardware change in migrating from the PCM6240-Q1 to the PCM6340-Q1 is on pins 3, 4, and 5 as highlighted in Figure 2-2.

Software Compatibility: The PCM6xx0-Q1 family uses exactly the same data and control interfaces, similar register map definitions, and have the same digital timing requirements. This high level of software compatibility allows the designer to re-use the application software or driver with ease across platforms and thereby save time and development cost.
