SYN6288E

Beijing Yu tone World Tech · Audio Interface ICs · QFP-32(7x7)

SYN6288E from Beijing Yu tone World Tech, in a QFP-32(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 XOUT output High-speed crystal oscillator output.
2 VDDA power_in Positive supply of the internal regulator.
3 TxD output UART data transmit; initial baud rate 9600bps.
4 RxD input UART data receive; initial baud rate 9600bps.
5 VSSIO0 power_in Negative supply (ground) of bus module 0.
6 VDDIO0 power_in Positive supply of bus module 0.
7 VSSIO0 power_in Negative supply (ground) of bus module 0.
8 Ready/Busy-STATUS output Low level means chip idle and able to receive commands and data; high level means chip busy synthesizing and playing speech.
9 Res. input Res pin; must be wired per the datasheet section 10.7 (should reach high level before the supply groups ramp up).
10 VDDIO1 power_in Positive supply of bus module 1.
11 VSSIO1 power_in Negative supply (ground) of bus module 1.
12 VSSPP power_in Negative supply of the voice output module.
13 BP0 output Push-pull DAC speech output 1; drive/sink current 150mA at VDD=3V.
14 VDDPP power_in Positive supply of the voice output module, can be powered independently of other supply groups.
15 BN0 output Push-pull DAC speech output 2; drive/sink current 150mA at VDD=3V.
16 VSSPP power_in Negative supply of the voice output module.
17 NC unconnected No connection.
18 NC unconnected No connection.
19 NC unconnected No connection.
20 NC unconnected No connection.
21 NC unconnected No connection.
22 NC unconnected No connection.
23 NC unconnected No connection.
24 VSS power_in Negative supply, integral with the chip substrate; must be connected to PCB ground (GND) or VSS.
25 VSSIO2 power_in Negative supply (ground) of bus module 2.
26 CVSS power_in Negative supply of the processor.
27 RST input Chip reset, active low.
28 VDDIO2 power_in Positive supply of bus module 2.
29 CVDD power_in Positive supply of the processor.
30 REGOUT power_out Regulated voltage output (linear regulator) of 2.8V±0.2V (2.6V to 3.0V), 20mA output current, supplying CVDD.
31 VSSA power_in Negative supply of the internal regulator.
32 XIN input High-speed crystal oscillator input.
