High Speed UART interface

The JODY-W2 series modules support a high-speed Universal Asynchronous Receiver/Transmitter
(UART) interface in compliance with the industry standard 16550 specification. The main features of
the UART interface are:

•

FIFO mode permanently selected for transmit and receive operations

•

Two pins for transmit and receive operations

•

Two flow control pins (RTS/CTS)

•

Interrupt triggers for low-power, high throughput operation

•

Supports standard baud rates and high throughput up to 4 Mbit/s. The default baud rate after

reset is 3000000 baud.

The UART interface operation includes:

•

Uploading the firmware to the module

•

Bluetooth data

Table 11: UART signal description

High Speed UART signals are powered by the

VIO

voltage domain.

PCM - Audio interface

JODY-W2 series modules provide one bi-directional 4-wire PCM digital audio interface that can be
used for digital audio communication with external digital audio devices as an audio codec. The PCM
interface supports:

•

Master or slave mode

•

PCM bit width size of 8 bit or 16 bit

•

Up to 4 slots with configurable bit width and start positions

•

Short frame and long frame synchronization

The PCM signals are powered by the VIO voltage domain.

Low power oscillator

For professional grade modules, an optional external low-frequency clock for low-power mode timing
can be connected to the

LPO_IN

pin. The external LPO must meet the requirements listed in

If no external sleep clock is used, leave this pin unconnected.
