4-bit uC base Voice Synthesizer (OTP)
Nuvoton Technology Corp. Release Date: Nov-2014 http://www.nuvoton.com/ Revision A1 - 2 - Content
Nuvoton Technology Corp. Release Date: Nov-2014 http://www.nuvoton.com/ Revision A1 - 3 - 1. INTRODUCTION N5132 builds in 4 -bit uC. Its 2Mbit OTP memory size covers up to 60 seconds voice duration scope. In the system frequency, 8MHz, N5132 can operate at 2.2~5.5V that is suitable for 2 or 3 batteries. In addition, N5132 provides H/W voice synthesizer for 1 -ch voice playback. Meantime, N5132 has PWM output to drive speaker, WDT and LVR. N5132 not just provides blank chip but also support on line program model to save customer ’s program schedule. Meanwhile, N5132 provides bare die and SOP20 package form for variou s applications. 2. FEATURE VDD: 2.2 ~ 5.5V (for 2 or 3 batteries application) Build in 2Mbit OTP System frequency (Ring Type oscillator): 8MHz at 2.2~5.5V (Rosc = 150 K ohm) H/W Voice Synthesizer 1-ch voice Algorithm: 5 -bit MDM Build in PWM to drive speaker directly. It has 4 -level volume control Provides STOP mode to stop entire IC operation Provides CPU mode interface to communicate with external MCU Watch Dog Timer (WDT) Low Voltage Reset (LVR) Offer easy use development tools Voice combination and playback NV-513X voice module USB writer Package type: Die form or SOP20

PIN DESCRIPTION PIN Name IO Function Description BP10~BP13 I/O Port 1 is a bi-directional I/O por t as inter face of program; or CPU mode interface (SPI). BP10: SSB, BP11: SCLK, BP12: MISO, BP13: MOSI BP32, BP33 I/O 250Hz frequency output control port to measure the deviation of system frequency. VDD, VDD1 - Power VSS, VSS1 - Ground V33O - 3.3V output, only for internal usage PWM+ O PWM driver positive output PWM- O PWM driver negative output VDD_SPK - Power for PWM driver VSS_SPK - Ground for PWM driver OSC I Ring type oscillator . This port connects to Ring then ground. /RESET I Chip reset TEST I Test port with internal pull high. It shares with program interface. VPP - Only use in OTP program mode Note: As program OTP , BP10 ~ BP13, VDD, VSS, /RESET , TEST and VPP will be used.

Nuvoton Technology Corp. Release Date: Nov-2014 http://www.nuvoton.com/ Revision A1 - 7 - 5.2 2-battery Application Circuit Note: 1. The Rosc typical value is 150K ohm at 8MHz. It should be connected to GND (VSS) 2. In PCB layout, VSS_SPK and VSS should be connected; VDD_SPK and VDD should be connected . 3. 4.7uF is optional for power stability. I ts value is depends on application. 5. In light loading application, the 0.1uF in VDD and GND is must to filter po wer noise 6. The 0.1uF in /RESET and GND is optional for power reset stability 7. CPU interface (SPI) defines as: BP10: SSB, BP11: SCLK, BP12: MISO, BP13: MOSI 8. As BP32 be grounding, it can control BP33 outp ut a 250Hz standard frequency for the purpose of system frequency deviation measurement . As the value higher than 250Hz, means system frequency too fast , then adjust Rosc value be higher to slow down ; vise verse, as it lower than 2 50Hz, means system frequency too slow , then adjust Rosc value be lower to speed up it. 9. The above application circuits are for reference only. No warranty for mass production.
