Product description:

1 Features

Voice content is stored in the plug-in SPI FLASH; Rewritable 100,000 times; save time more than 100 years;

Simple and easy mode of operation (key module; serial line; wire serial; three-wire serial interface);

It can be stored in WAV; ADPCM format files; playback voice can be combined to save storage space;

Two output modes (DAC and PWM output, DAC output external amplifiers, PWM can directly drive 0.5W speaker);

Can plug 1Mbit ~ 128Mbit capacity SPI FLASH memory, voice time length of 40 seconds to 2560 seconds (6K sampling rate calculation);

Flexible segment playback operation; can easily control any segment voice playback; voice combination greatly save space;

It supports dual-channel voice simultaneously playback, support slogan spots; (to be customized)

Good sound quality; high performance; inexpensive;

Small size; modular design as the standard DIP16 package; easy to use; flexible application;

There are busy signal level indication;

Built-in DSP high speed processor; very short response time; receiving a complete instruction to the player; the response time in the microsecond range control;

Voltage operating range of 2.7V ~ 3.6V;

Quiescent current of 20uA, can meet most low-power applications;

Intelligent sleep mode within one second after it finishes playing the voice automatically enter sleep;

Sound and mature supporting tools and software tools to manipulate and control the entire chip-based humane simplified operating concept;

Products may be provided in the form of the module to the user; can also provide solutions; which the user need only purchase the master voice core

Sheet, flexible application;

2 Features

JTM020VS Series supports a variety of common brands on the market SPI FLASH, such as 25P series. 25X series. 25L

Series, support 1Mbit ~ 128Mbit capacity, according to the voice capacity can be flexibly configured to replace the FLASH chip.

DAC output and PWM output JTM020VS with high sound quality. PWM output can support 0.5W amplifier, loudness

Adjustable JTM020VS support intelligent voice combination play; Can save voice space; another can be defined under the Freedom of need

Quiet length of time; embedded speech paragraphs go; support 3328 segments combined voice paragraphs; the user by pressing a button or

By sending eight serial address control play any segment, stop, loop, etc. There output busy signal.

Key module: Every single key can be independently configured for a variety of key trigger modes: Edge can interrupt triggered repeatedly edge

Should not interrupt the trigger; trigger level can be recycled; trigger level is not circulating; play / stop; on a non-circulation; the next

The first does not cycle on a cycle, next cycle.

Serial line: to control the voice module via the master CPU sends a single line serial The coding rate per bit in 600us ~ 8ms.

Between, encoding in accordance with the level of the duty ratio of 1: 3 mode definition data 0 or 1.

Three-wire serial interface: send three-wire serial interface coding by the host CPU to control every bit rate speech coding module in 60us ~ 6ms.

Between, according to the transmission encoding chip select, clock and data.

Remarks:

  1. Full length 6K based voice sampling rate calculation, the general application of the sampling rate is greater than 8K, so the voice length is only for reference.

  2. Mix a dozen X column is not supported, fight Support mix playback.

  3. DIP16 package module is based on the design, but also can be customized packaging, or in the form of chips used in the user's board.
