GPT1001A
GENERAL TOUCH SENSOR CONTROLLER
1. GENERAL DESCRIPTION
The GPT1001A, a general purpose touch sensor controller, equips
an 8-bit CMOS microprocessor, 8K-byte embedded flash, and
256-byte working SRAM. It allows the control of 24 IOs
configurable as capacitive sensing buttons or GPIOs. Moreover,
three PWMs are built-in to support hardware LED control with hold
and dimming function. The PWM can output to IOB or IOC
individually to produce fancy LED effect with simple program. To
communicate with host devices, the GPT1001A equips SPI or I2C
interfaces. The GPT1001A operates at a wide voltage range of
2.6V – 5.5V. The maximum CPU frequency runs up to 8MHz.
Sleep mode and halt mode are also provided to optimize system
performance and power consumption. The In-Circuit Emulation
(ICE) function is built-in with on-chip re-programmable non-volatile
memory.
2. FEATURES
8-bit microprocessor with ICE function
─ Embedded flash 8K bytes
─ SRAM 256 bytes
Clock
─ Built-in 8MHz ROSC
─ Built-in 30KHz ROSC for time-base function
─ /1, /2, /4, /8, /16, /32 of 8MHz clock output for CPU
Operating Voltage: 2.6V ~ 5.5V
Industrial Temperature Range: -40℃ ~ 85℃
Operation Modes
─ Operating mode, Sleep mode, and Halt mode
Timer/Counter
─ 8-bit timers with selective clock sources
─ Programmable auto sleep timer
Power management for system reliability
─ Low-Voltage-Reset function
─ Power-On-Reset function
─ Watchdog reset (derived from 30KHz clock)
Eight Interrupt /Wakeup sources (INT /WP)
─ Timer overflow
─ Counter
─ IOA[7:0], IOB[7:0], IOC[7:0] key-changed
─ Serial interface interrupt
─ Sensor counter interrupt
─ External interrupt
Up to 24 I/Os
─ IOA[7:0]:programmable as GPIO/Wakeup-able IO/external
INT
─ IOB[7:0]:programmable as GPIO/Wakeup-able IO/PWM
output
─ IOC[7:0]:programmable as GPIO/Wakeup-able IO/PWM
output
Capacitive sensors
─ Supports max. 24 capacitive sensor I/Os of individual keys.
─ Built-in auto sleep/wakeup function to minimize power
consumption during sensing operation.
Three PWMs with programmable hold-time and fade-out time
for LED drive
SPI slave interface supports different polarity and phase modes
I2C slave interface
Note:
(1)The frequency deviation for built-in 8MHz ROSC is +-10% at room
temperature.
(2)The frequency deviation for built-in 30KHz ROSC is +-15% at room
temperature.
3. APPLICATION FIELD
Home appliance, MP3 capacitive touch pad controller, toy,
general touch application, or general purpose controller.
