2 / 75 page  ISD5216 - 2 - 1. GENERAL DESCRIPTION The ChipCorder ISD5216 is an 8 to 16 minute Voice and Data Record and Playback system with integrated Voice band CODEC. The device works on a single 2.7V to 3.3V supply, and has fully integrated system functions, including: AGC, microphone preamplifier, speaker driver, memory and CODEC. The CODEC meets the PCM conformance specification of the G.714 recommendation. Its μ- Law and A-Law compander meets the specification of the ITU-T G.711 recommendation. 2. FEATURES • Single Supply 2.7 to 3.3 Volt operation • Voice and digital data record and playback system on a single chip • Industry-leading sound quality • Low voltage operation • Message management • Fully integrated system functions • Flexible architecture • Nonvolatile message storage • Configurable ChipCorder sampling rates of 4 kHz, 5.3kHz, 6.4 kHz and 8kHz • 8, 10, 12 and 16 minutes duration • External or internal Voice recorder clock • I2C serial interface (400kHz) • Configurable analog paths • 2.2V Microphone Bias Pin • 100 year message retention (typical) • 100K analog record cycles (typical) • 10K digital record cycles (typical) • Full-duplex (not in I2S mode) single channel speech CODEC with: o External 13.824 MHz, 27.648 MHz, 20.48 MHz or 40.96 MHz master clock o I2S and PCM digital audio interface ports o Serial transfer data rate from 64 to 3072 Kbps o Short and Long frame sync formats o 2s complement and signed magnitude data format o Complete μ-Law and A-Law companding o Linear 14 bit ΔΣ PCM CODEC-filter for A/D and D/A converter o 8 kHz or 44.1 kHz – 48 kHz digital audio sampling rate options o Analog receive and transmit gain adjust o Configurable setup through the I2C interface |
