PIN DESCRIPTION PIN NAME PIN # FUNCTION SOIC / PDIP 1 Slave Select: This input, when LOW, will select the ISD4004 device. MOSI 2 Master Out Slave IN: This is the serial input to the ISD4004 device when it is configured as slave. The master microcontroller places data on the MOSI line one half-cycle before the rising edge of SCLK for clocking into the device. MISO 3 Master In Slave Out: This is the serial output of the ISD4004 device. This output goes into a high-impedance state if the device is not selected. VSSA / VSSD 11, 12, 23 / 4 Ground: The ISD4004 series utilizes separate analog and digital ground busses. The analog ground (VSSA) pins should be tied together as close as possible and connected through a low-impedance path to power supply ground. The digital ground (VSSD) pin should be connected through a separate low-impedance path to power supply ground. These ground paths should be large enough to ensure that the impedance between the VSSA pins and the VSSD pin is less than 3 Ω. The backside of the die is connected to VSS through the substrate. For chip-on-board design, the die attach area must be connected to VSS or left floating. NC 5-10, 15, 1922 Not connected AUD OUT [1] 13 Audio Output: This pin provides an audio output of the stored data and is recommended be AC coupled. It is capable of driving a 5 KΩ impedance REXT. AM CAP 14 AutoMute™ Feature: The AutoMute feature only applies for playback operation and helps to minimize noise (with 6 dB of attenuation) when there is no signal (i.e. during periods of silence). A 1 µF capacitor to ground is recommended to connect to the AM CAP pin. This capacitor becomes a part of an internal peak detector which senses the signal amplitude. This peak level is compared to an internally set threshold to determine the AutoMute trip point. For large signals, the AutoMute attenuation is set to 0 dB automatically but 6 dB of attenuation occurs for silence. The 1 µF capacitor also affects the rate at which the AutoMute feature changes with the signal amplitude (or the attack time). The AutoMute feature can be disabled by connecting the AM CAP pin directly to VCCA.. SS [1] The AUD OUT pin is always at 1.2 volts when the device is powered up. When in playback, the output buffer connected to this pin can drive a load as small as 5 KΩ. When in record, a built-in resistor connects AUD OUT to the internal 1.2-volt analog ground supply. This resistor is approximately 850 KΩ, but will vary somewhat according to the sample rate of the device. This relatively high impedance allows this pin to be connected to an audio bus without loading it down. Jun 28, 2021 Page 6 of 34 Rev1.5 ISD4004 PIN NAME PIN # FUNCTION SOIC / PDIP ANA IN- 16 Inverting Analog Input: This pin transfers the signal into the device during recording via differential-input mode. In this differential-input mode, a 16 mVp-p maximum input signal should be capacitively coupled to ANA IN- for optimal signal quality, as shown in Figure 1: ANA IN Modes. This capacitor value should be equal to that used on ANA IN+ pin. The input impedance at ANA IN- is normally 56 KΩ. In the single-ended mode, ANA IN- should be capacitively coupled to VSSA through a capacitor equal to that used on the ANA IN+ pin. ANA IN+ 17 Non-Inverting Analog Input: This pin is the non-inverting analog input that transfers the signal to the device for recording. The analog input amplifier can be driven single ended or differentially. In the single-ended input mode, a 32 mVp-p (peak-to-peak) maximum signal should be capacitively connected to this pin for optimal signal quality. The external capacitor associated with ANA IN+ together with the 3 KΩ input impedance are selected to give cutoff at the low frequency end of the voice passband. In the differential-input mode, the maximum input signal at ANA IN+ should be 16 mVp-p capacitively coupled for optimal signal quality. The circuit connections for the two modes are shown in Figure 1. VCCA / VCCD 18 / 27 Supply Voltage: To minimize noises, the analog and digital circuits in the ISD4004 devices use separate power busses. These +3V busses are brought out to separate pins and should be tied together as close to the supply as possible. In addition, these supplies should be decoupled as close to the package as possible. RAC 24 Row Address Clock: This is an open drain output that provides the signal of a ROW with a 200 ms period for 8 KHz sampling frequency. (This represents a single row of memory.) This signal stays HIGH for 175 ms and stays LOW for 25 ms when it reaches the end of a row. The RAC pin stays HIGH for 109.37 µsec and stays LOW for 15.63 µsec in Message Cueing mode (see Message Cueing section for detailed description). Refer to the AC Parameters table for RAC timing information at other sample rates. When a record command is first initiated, the RAC pin remains HIGH for an extra TRACL period. This is due to the need of loading the internal sample and hold circuits in the device. This pin can be used for message management techniques. A pull-up resistor is required to connect this pin to other device. INT 25 Interrupt: This is an open drain output pin. This pin goes LOW and stays LOW when an Overflow (OVF) or End of Message (EOM) marker is detected. Each operation that ends with an EOM or OVF will generate an interrupt. The interrupt will be cleared the next time an SPI cycle is initiated. The interrupt status can also be read by an RINT instruction. A pull-up resistor is required to connect this pin to other device. Overflow Flag (OVF) – The Overflow flag indicates that the end of memory has been reached during a record or playback operation. End of Message (EOM) – The End of Message flag is set only during playback operation when an EOM is found. There are eight EOM flag position options per row. Jun 28, 2021 Page 7 of 34 Rev1.5 ISD4004 PIN NAME PIN # FUNCTION SOIC / PDIP XCLK 26 External Clock Input: The ISD4004 series is configured at the factory with an internal sampling clock frequency centered to ±1 percent of specification. The frequency is then maintained to a variation of ±2.25 percent over the entire commercial temperature and operating voltage ranges. The internal clock has a –6/+4 percent tolerance over the industrial temperature and voltage ranges. A regulated power supply is recommended for industrial temperature range parts. If greater precision is required, the device can be clocked through the XCLK pin as follows: Part Number Sample Rate Required Clock ISD4004-08M 8.0 kHz 1024 kHz ISD4004-10M 6.4 kHz 819.2 kHz ISD4004-12M 5.3 kHz 682.7 kHz ISD4004-16M 4.0 kHz 512 kHz These recommended clock rates should not be varied because the antialiasing and smoothing filters are fixed. Otherwise, aliasing problems can occur if the sample rate differs from the one recommended. The duty cycle on the input clock is not critical, as the clock is immediately divided by two. If the XCLK is not used, this input must be connected to ground. SCLK Jun 28, 2021 28 Serial Clock: This is the input clock to the ISD4004 device. It is generated by the master device (typically microcontoller) and is used to synchronize the data transfer in and out of the device through the MOSI and MISO lines, respectively. Data is latched into the ISD4004 on the rising edge of SCLK and shifted out of the device on the falling edge of SCLK.

FUNCTIONAL DESCRIPTION 6.1. DETAILED DESCRIPTION Audio Quality The Nuvoton’s ISD4004 ChipCorder® series is offered at 8.0, 6.4, 5.3 and 4.0 kHz sampling frequencies, allowing the user a choice of speech quality options. Increasing the sampling frequency will produce better sound quality, but affects duration. Please refer to Table 1: Product Summary for details. Analog speech samples are stored directly into on-chip non-volatile memory without the digitization and compression associated with other solutions. Direct analog storage provides higher quality reproduction of voice, music, tones, and sound effects than other solid-state solutions. Duration The ISD4004 Series is a single-chip solution with 8-, 10-, 12-, and 16-minute duration. TABLE 1: PRODUCT SUMMARY OF ISD4004 SERIES Part Number Duration (Minutes) Sample Rate (kHz) Typical Filter Pass Band (kHz) * ISD4004-08M 8 8.0 3.4 ISD4004-10M 10 6.4 2.7 ISD4004-12M 12 5.3 2.3 ISD4004-16M 16 4.0 1.7 * This is the –3dB point. This parameter is not checked during production testing and may vary due to process variations and other factors. Therefore, the customer should not rely upon this value for testing purposes. Flash Storage The ISD4004 series utilizes on-chip Flash memory, providing zero-power message storage. The message is retained for up to 100 years typically without power. In addition, the device can be rerecorded typically over 100,000 times. Memory Architecture The ISD4004 series contains a total of 3,840K Flash memory cells, which is organized as 2,400 rows of 1,600 cells each. The address bits (A0-A15) are used to access various rows for multiple messages of different durations. Jun 28, 2021 Page 10 of 34 Rev1.5 ISD4004 Microcontroller Interface A four-wire (SCLK, MOSI, MISO & SS ) SPI interface is provided for controlling and addressing functions. The ISD4004 is configured to operate as a peripheral slave device, with a microcontrollerbased SPI bus interface. Read and write operations are controlled through this SPI interface. An interrupt signal ( INT ) and internal read only Status Register are provided for handshake purposes. Programming The ISD4004 series is also ideal for playback-only applications, where single- or multiple-messages playback is controlled through the SPI port. Once the desired message configuration is created, duplicates can easily be generated via a programmer. 6.2. SERIAL PERIPHERAL INTERFACE (SPI) DESCRIPTION The ISD4004 series operates via SPI serial interface with the following protocol. First, the data transfer protocol assumes that the microcontroller’s SPI shift registers are clocked on the falling edge of the SCLK. However, for the ISD4004, the protocols are as follows: 1. All serial data transfers begin with the falling edge of SS pin. 2. SS is held LOW during all serial communications and held HIGH between instructions. 3. Data is clocked in on the rising edge of the SCLK signal and clocked out on the falling edge of the SCLK signal, with LSB first. 4. Playback and record operations are initiated when the device is enabled by asserting the SS pin LOW, shifting in an opcode and an address data to the ISD4004 device (refer to the Opcode Summary in the following page). 5. The opcodes contain and . 6. Each operation that ends with an EOM or Overflow will generate an interrupt. The Interrupt will be cleared the next time a SPI cycle is initiated. 7. As Interrupt data is shifted out of the MISO pin, while address and control data are simultaneously shifted into the MOSI pin. Care should be taken such that the data shifted in is compatible with current system operation. Because it is possible to read an interrupt data and start a new operation within the same SPI cycle. 8. An operation begins with the RUN bit set and ends with the RUN bit reset. 9. All operations begin after the rising edge of SS . Jun 28, 2021 Page 11 of 34 Rev1.5 ISD4004 6.2.1 OPCODES The available Opcodes are summarized as follows: TABLE 2: OPCODE SUMMARY Instructions OpCodes Address (16 bits) POWERUP SETPLAY PLAY SETREC REC SETMC Descriptions Control bits (8 bits) XXX C0 C1 C2 C3 C4 XXX 0 0 1 0 0 Power-Up: Device will be ready for an operation after TPUD.

STOP XXX 0 1 1 X 0 Stops the current operation. STOPPWRDN XXX X 1 0 X 0 Stops the current operation and enters into standby (powerdown) mode. RINT [ 2] XXX 0 1 X 0 Read Interrupt status bits: Overflow and EOM. MC 1 Notes: C0 = Message cueing C1 = Ignore address bit C2 = Master power control C3 = Record or playback operation C4 = Enable or disable an operation [1] Message Cueing can be selected only at the beginning of a playback operation. [2] As the Interrupt data is shifted out of the ISD4004, control and address data are being shifted in. Care should be taken such that the data shifted in is compatible with current system operation. It is possible to read interrupt data and start a new operation at the same time. See Figures 5 - 8 for references.

For consecutive playback or record, IAB should be changed to a 1 before the end of that row (see RAC timing). Otherwise the ISD4004 will repeat the operation from the same row address. For memory management, the Row Address Clock (RAC) signal and IAB can be used to move around the memory segments. Jun 28, 2021 Page 14 of 34 Rev1.5 ISD4004 Message Cueing Message cueing (MC) allows the user to skip through messages, without knowing the actual physical location of the messages. It will stop when an EOM marker is reached. Then, the internal address counter will point to the next message. Also, it will enter into OVF condition when it reaches the end of memory. In this mode, the messages are skipped 1,600 times faster than the normal playback mode. Power-Up Sequence The ISD4004 will be ready for an operation after power-up command is sent and followed by the TPUD timing (25 ms for 8 KHz sampling rate). Refer to the AC timing table for other TPUD values with respect to different sampling rates. The following sequences are recommended for optimized Record and Playback operations. Record Mode 1. Send POWERUP command. 2. Wait TPUD (power-up delay). 3. Send POWERUP command. 4. Wait 2 x TPUD (power-up delay). 5. a). Send SETREC command with address xx, or b). Send REC command (recording from current location). 6. Send STOP command to stop recording. 7. Wait TSTOP/PAUSE. For 3 & 4), please refer to Apps Brief 39A: recorded pop elimination in the ISD4000 series. For 5.a), the device will start recording at address xx and will generate an interrupt when an overflow (end of memory array) is reached, if no STOP command is sent before that. Then, it will automatic stop recording operation. Playback Mode 1. Send POWERUP command 2. Wait TPUD (power-up delay) 3. a). Send SETPLAY command with address xx, or b). Send PLAY command (playback from current location). 4. a). Send STOP command to halt the playback operation, or b). Wait for playback operation to stop automatically, when an EOM or OVF is reached. 5. Wait TSTOP/PAUSE. For 3.a), the device will start playback at address xx and it will generate an interrupt when an EOM or OVF is reached. It will then stop playback operation.

[2] All Min/Max limits are guaranteed by Nuvoton via electrical testing or characterization. Not all specifications are 100 percent tested. [3] Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions) [4] Single-ended input mode. In the differential input mode, VIN maximum for ANA IN+ and ANA IN- is 16 mVp-p. [5] Sampling Frequency can vary as much as ±2.25 percent over the commercial temperature and voltage ranges, and –6/+4 percent over the industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions) [6] Playback and Record Duration can vary as much as ±2.25 percent over the commercial temperature and voltage ranges, and –6/+4 percent over the industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions) [7] Filter specification applies to the antialiasing filter and the smoothing filter. Therefore, from input to output, expect a 6 dB drop by nature of passing through both filters. [8] The typical output voltage will be approximately 450 mVp-p with VIN at 32 mVp-p. [9] For optimal signal quality, this maximum limit is recommended. [10] When a record command is sent, T RAC = TRAC + TRACL on the first row address. [11] Measured with AutoMute feature disabled.
