It includes an audio decoder with a high performance DSP with embedded RAM, ADPCM/AG record capabilities and USB interface for downloading music and uploading voice recordings. ATJ2075 also provides an interface to S/PDIF audio data input, flash memory, LED/LCD, button and switch inputs, headphone, and microphone, and FM radio control. The ATJ2075's programmable architecture supports the MP3 and WMA and other digital audio standards. For devices like USB Flash Disk, the ATJ2075 can act as a USB mass storage slave device to personal computer system. The ATJ2075 has low power consumption to allow long battery life and an efficient flexible on-chip DC-DC converter that allows many different battery configurations, including 1xAA, 1xAAA, 2xAA,2xAAA.

Microphone pre-amplifier has 35db gain at least for suitable recording volume so the noise of microphone power supply must be very low. It is composed of a regulator and an external first order RC LPF. AGC function is implemented by a variable gain amplifier and 4 register bits (MCU code control). The ADC adopts switched-capacitor successive approximation method. Its input is from microphone preamplifier's output. Function enable, sampling frequency select, and some other control signals are all from one register. DC DB DA D9 D6 D5 A D C AVCC AGND DE_4 1.5v MICIN MICOUT D4_[3:0] AGCI 5.8 SPDIF Interface The AES/EBU interface is a means for serially communicating digital audio data through one single transmission line. It provides two channels for audio data, a method for communicating control information, and has error detection capabilities. The control information is transmitted as one bit per sample and accumulates in a block structure. The data is bi-phase encoded, which enables the receiver to extract a clock from the data . Coding violations, defined as preambles, are used to identify sample and block boundaries. 2 8-level by 8-bit FIFO are used to buffer data for TX and RX. After received 192 frame- four bytes of channel status was appended into the RX FIFO. When TX FIFO is empty and SPDIF is enabled, 0 is send out for all frame.

Sub-frame Format 5.9 Power Management Unit (PMU) PMU consists of DC-DC converter and regulator and battery monitor. ATJ2075 need two power trails if work rightly, VDD (Core Power) and VCC (I/O Power). The power level is decided by external voltage-divided resistance network . Due to describe clearly , we assume VDD=2.35V, VCC=3.15V. There are two battery modes with ATJ2075, one-battery mode and two-battery mode, selected by BATSEL. In one-battery mode, if pin VBAT > 0.8V, some internal circuit (C1) begin to work first and it will rise up VDD. When VDD reaches 2.35V, that internal circuit (C1) stops and another circuit (C2) takes over the PFM for both VDD and VCC DC-DC converter. In two-battery mode, if pin VBAT > 1.3V, the internal regulator is enabled to supply VDD. If 0.8V < VBAT < 1.3V, C2 will stimulate VDD DC-DC converter to maintain VDD. The judgement between VBAT and Page 27 of 46 Actions Semiconductor Co.,LTD Data Sheet 1.3V must have hysteresis for preventing ATJ2075 from unstable toggle between regulator mode and DC-DC mode. The VCC DC-DC converter always runs to maintain VCC. Battery monitor compares the battery voltage at the VBAT pin with four reference voltage pins named VL0, VL1, VL2, VL3. The four reference voltages are decided by external resistance network. For normal dry battery (1.5V) , the value can be : 1.4V, 1.3V, 1.15V, and 1.05V. If VBAT < VL3, ATJ2075 will go into STANDBY mode; If VBAT < 0.8V, ATJ2075 will go into OFF mode, but the low frequency OSC and RTC timer are still active. You can disable the clock of block when you do not use that block. Even more you can stop all the clock, but low frequency OSC, while you design appropriately.

Low frequency oscillator will begin to work too. After a duration , POR(Power On Reset) will deassert . ATJ2075 finishes Power Up sequence . If pin RESET- is not assert, MCU will run from address=0x8000. Boot code at address=0x8000 will be as the following: JP 8003h LD A, 01h Page 28 of 46 Actions Semiconductor Co.,LTD ATJ2075 OUT (04h), A JP Start ......

When a key is pressed, pin KEYINn connecting the key will be found low level. There are 12 internal 8-bit registers for key value latch per scan. But only another one register (Key Scan Data Register ) for MCU to access key value . Those 12 internal registers are mapped into this register, and an internal pointer is used to point to the current register to return scan data when read. Any IO write to this register will clear the internal register, and the pointer will increase by 1 and point to the next register after read is performed.
