It contains an 8051 micro-controller, Low-Speed USB SIE, Transceiver and data FIFO, build-in 3.3V regulator, on-chip 16K bytes Mask ROM and internal 256 bytes data RAM, Time Capture circuit, Base Timer, programmable Watch-dog Timer and Wake-up Timer, support multiple type LED driving capability for different application, built-in internal 32KHz oscillator, POR and LVR circuit saving your external components cost. Instead of external crystal, the XA2001 built in an on-chip high accuracy 6MHz RC Resonator for system and USB SIE. Up to 36 selectable GPIO are provided, while the source current of Port0, Port1, Port2, and Port3 can be configured smaller to support carbon membrane. Application can cover such items as Keyboards and others. 1 V1.0 Pad Configuration XA2001 2 Block Diagram RSTB V33 V DD GND 6MHz OSC Power Down Mode Controller Wake-up Timer 32KHz OSC Low Voltage Reset Power On Reset 3.3V REGULATOR XA2001 8051 Interrupt Controller 16K Bytes MASK ROM 256 Bytes DATA RAM Watch Dog Timer Two Base Timer Time Capture USB Transceiver USB SIE Serial Bus Manager USB Data FIFO I/O PORTs VDP/P45 VDM/P46/EXT0 P40 - P42/LED00 - 02 P00 - P07 P10 - P17 P20 - P27 P30 - P33, P35/LED10 - 13, 15 P36 - P37/BLED0 - 1 3 XA2001 Pad Description PAD No. Designation I/O Description 1 P46/VDM/EXT0 I/O Bi-directional I/O pin shared with VDM 2 P30/LED10 I/O Bi-directional I/O pin 3 P31/LED11 I/O Bi-directional I/O pin 4 P32/LED12 I/O Bi-directional I/O pin 5 P33/LED13 I/O Bi-directional I/O pin 6 P35/LED15 I/O Bi-directional I/O pin 7 P36/BLED0 I/O Bi-directional I/O pin 8 P37/BLED1 I/O Bi-directional I/O pin 9 RSTB I For external Reset Input with 55K (RRST) Ohm pull high resistance 10 P00 I/O Bi-directional I/O pin 11 P01 I/O Bi-directional I/O pin 12 P02 I/O Bi-directional I/O pin 13 P03 I/O Bi-directional I/O pin 14 P04 I/O Bi-directional I/O pin 15 P05 I/O Bi-directional I/O pin 16 P06 I/O Bi-directional I/O pin 17 P07 I/O Bi-directional I/O pin 18 P10 I/O Bi-directional I/O pin 19 P11 I/O Bi-directional I/O pin 20 P12 I/O Bi-directional I/O pin 21 P13 I/O Bi-directional I/O pin 22 P14 I/O Bi-directional I/O pin 23 P15/TC0 I/O Bi-directional I/O pin 24 P16 I/O Bi-directional I/O pin 25 VPP P Voltage input (VPP) 26 P17 I/O Bi-directional I/O pin 27 P20 I/O Bi-directional I/O pin 28 P21 I/O Bi-directional I/O pin 29 P22 I/O Bi-directional I/O pin 30 P23 I/O Bi-directional I/O pin 31 P24 I/O Bi-directional I/O pin 32 P25 I/O Bi-directional I/O pin 33 P26 I/O Bi-directional I/O pin 34 P27 I/O Bi-directional I/O pin 35 P40/LED00 I/O Bi-directional I/O pin 36 P41/LED01 I/O Bi-directional I/O pin 37 P42/LED02 I/O Bi-directional I/O pin 38 VREG_OUT_RC P Regulator output(+1.8V) 39 VCC P Regulator output(+1.8V) 40 VDD P Power supply (5V) 41 VDDR P Regulator output (+3.3V) 42 GND P Ground 43 GND P Ground 44 GND P Ground 45 VDDR P Regulator output (+3.3V) 46 P45/VDP I/O Bi-directional I/O pin shared with VDP 4 XA2001 Functional Description 1. Memory 1.1. Memory Allocation There are 16K bytes Program Memory and 256 bytes Data Memory. These features are described as followed: 1.2. Program Memory The XA2001 embeds 16K Bytes (0000H - 3FFFH) on-chip program memory for program code. 1.3. Data Memory The XA2001 provides additional Bytes of RAM space for increased data parameter handling, high level language usage. The XA2001 has internal data memory that is mapped into three separate segments. The three segments are: 1. The Lower 128 bytes of RAM (addresses 00H to 7FH) are directly and indirectly addressable. 2. The Upper 128 bytes of RAM (addresses 80H to FFH) are indir.
