TC9350BFN-T00,TC9350BFN-T01
TOSHIBA CMOS Type Integrated Circuit Silicon Monolithic
TC9350BFN-T00,TC9350BFN-T01
USB Mouse Controller IC
The TC9350BFN is a USB 1.1 mouse controller IC.
It can communicate with Agilent's ADNS-2610 optical mouse
sensor.
Features
• Conforms to USB HID specification version 1.1
• Supports Agilent's ADNS-2610 optical mouse sensor.
• The TC9350BFN-T00 enables the built-in pull-up resistors of
the encoder input pins (PT3A, PT3B) when the mouse is
operating. It is suitable for a mechanical encoder. (The pull-up
resistors are disabled in suspend mode.)
Weight: 0.07 g (typ.)
• The TC9350BFN-T01 maintains the encoder input pins (PT3A, PT3B) always in high-impedance state. It is
suitable for an optical encoder (phototransistor and LED).
• Input/output ports
USB input/output driver: 2 pins (DP/DM)
Switch input: 3 pins (SW1, SW2, SW3)
Serial port clock output: 1 pin (SCK)
Serial data input/output: 1 pin (SDIO)
VDD control (for controlling the power supply for the ADNS-2610 optical mouse sensor): 1 pin (VCNT)
Encoder input: 2 pins (PT3A, PT3B)
LED driver: 1 pin (LED)
• Operating voltage: 4.35 to 5.25 V
• Operating temperature: 0 to 70°C
• Operating frequency: 6 MHz
• 0.6-µm CMOS monolithic IC
• Small package: SSOP16: SSOP16-P-225-0.65B

Scrolling and the scroll count
The following describes signal processing during scrolling:
<< Scroll signal processing >>
“+1 count” (If the transition of PT3A precedes that of PT3B)
(PT3A, PT3B) = (0,0) → (1,0) → (1,1) or (PT3A, PT3B) = (1,1) → (0,1) → (0,0)
“−1 count” (If the transition of PT3B precedes that of PT3A)
(PT3A, PT3B) = (0,0) → (0,1) → (1,1) or (PT3A, PT3B) = (1,1) → (1,0) → (0,0)
PT3A : PT3B
