Description and block diagram

STAMP0 is a microphone processor designed to interface digital microphones with PDM

interface, supporting a slave serial TDM output interface. STAMP0 has 4 PDM input lines

to support connections of up to 8 single-membrane digital microphones or up to 4 dual-

membrane microphones. Recombination of the dual-membrane microphone is embedded

in the device. An internal PLL provides stable clock references for the embedded

processing as well as for the external microphone arrays. An I²C interface allows setting

the internal registers for the control of the device depending on the application

requirements. STAMP0 is housed in a small VFQFPN 28-lead 5x5x1 mm package. The

STAMP0 internal architecture is illustrated in Figure 2: "Block diagram".
