SNJ54AHC86FK Datasheet Description The AT45D021 is a 5-volt only, serial interface Flash memory suitable for in-system reprogramming. Its 2,162,688 bits of memory are organized as 1024 pages of 264- bytes each. In addition to the main memory, the AT45D021 also contains two data SRAM buffers of 264-bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a serial interface to sequentially access its data. The simple serial interface facilitates hardware layout, increases system reliability, minimizes switching (continued) SNJ54AHC86FK Price The WM9704Q comprises a stere0 18-bit Codec, (that is, 2 ADCs and 2 DACs) plus two additional DACs. The WM9704Q also has a comprehensive analogue mixer with 4 sets of stereo inputs, plus phone, 2 microphone, and PC-beep inputs. On-chip reference circuits generate the necessary bias voltages for the device, and a bi-directional serial interface allows transfer of control data and DAC and ADC words to and from the AC'97 controller. The WM9704Q supports 18-bit resolution within the DAC and ADC functions, but the AC'97 serial interface specification allows any word length up t0 20- bits to be written to, or read from, the AC'97 Codec. These words are MSB justified, and any LSBs not used will simply default t0 0. Normally it is anticipated that 16-bit words will be used in most PC type systems. Therefore, for the DAC, 16-bit words will be downloaded into the Codec from the controller, along with padding of Os to make the 16-bit word up t0 20-bit length. In this case, the WM9704Q will process the 16-bit word along with o padding bits in the 2 LSB locations (to make 18- bit). At the ADC output, WM9704Q will provide an 18-bit word, again with Os in the two LSB locations (20-bit). The AC'97 controller will then ignore the 4 LSBs of the 20-bit word. When the WM9704Q is interrogated, it responds indicating it is an 18-bit device. SNJ54AHC86FK on stock
