8K BYTES OTP

MICRO-CONTROLLER WITH LCD

DRIVER

1. GENERAL DESCRIPTION

Generalplus GPL11B is a CMOS 8-bit single chip Micro-controller

containing LCD drivers, one-time programmable (OTP) ROM,

SRAM, I/O, timer/counter, PLL/ROSC, audio/remote control out,

and resistor to frequency converter (RFC) function, all in one chip.

The GPL11B is designed to drive LCD directly and perform efficient

controller function as well as arithmetic function.

With on-chip

crystal oscillator, the real-time clock can be easily achieved.

For

power savings, several power-down modes are controllable by

software.

The GPL11B is widely used for low power electronic

products,

e.g.

remote

controller

and

general-purpose

LCD

controller.

For more information about how to program GPL11B

OTP chip, please refer to Generalplus OTP/MTP Writer User’s

Manual.

2. FEATURES

Built-in Generalplus 8-bit CPU

- 128-byte SRAM

- 8K-byte OTP

- Working Voltage 2.4V ~ 5.5V (low voltage reset is disabled),

2.6V ~ 5.5V (low voltage reset is enabled)

- Maximum CPU speed 4MHz @ 2.4V

- CPU clock can be switched between High-Speed clock (PLL /

R-oscillator) divided by 2 / 4 / 8 / 16 or Low-speed clock

(32768Hz Crystal-oscillator / 32768 R-oscillator)

- Watchdog timer and illegal address reset circuit are always

enabled and will reset CPU if these events occur

- Eight wakeup sources (37.9K/N, 32768/N, TMO, EXT1, EXT2,

T2Hz, KEYC, NMI)

- Eight interrupt sources

Dual clock sources:

- Dual clock sources are controlled by two clock option pins

- High-Speed clock sources: PLL/R-oscillator

- Low-speed clock sources: 32768 Crystal / 32768 R-oscillator

- PLL clock = 4.85MHz

- IR carrier frequency = 37.9KHz

- Maximum system clock in PLL clock mode = 2.42MHz

Programmable LCD driver

- 48 byte Dual-port SRAM for LCD buffers

- LCD has 1/2 bias, 1/3 bias, 1/4 bias selections

- Maximum LCD 12x30 (360 dots), 11x30 (330 dots), 10x30

(300 dots), 9x32 (288 dots), 8x32 (256 dots), 5x32 (160 dots),

4x32 (128 dots), 3x32 (96 dots)

A 16-bit re-loadable timer/counter

Low voltage reset level is at 2.4V and can be disable by

LVROFF pin

Four Operating modes: Operating / WAIT / HALT /STANDBY

- Interrupt will wake CPU up

- Wakeup from CPU reset or next instruction is programmable

Built-in RFC (Resistor to Frequency Converter) function

I/O Port definition:

- 8 IOA, 4 shared pins with LCD Commons / Segments

- 8 IOB with key wakeup function, 5 shared pins with

LCD Commons / Segments / V3 / CUP3 / CUP4

Five Reset flags: watchdog, error address, power-on, external

reset, and low voltage

Low Power consumption:

- Operating current < 1mA @ 3.0V, CPU runs at 1.2MHz,

4.85MHz, PLL on

- Operating current < 500

μA @ 3.0V, CPU run 1MHz, 2MHz,

ROSC on

- Operating current < 20

μA @ 3.0V, CPU run 32KHz, 32768

crystal on, PLL off

- Halt current < 2

μA @ 3.0V, 1/8 duty, no load, 32768 crystal &

LCD on, PLL & CPU off

Serial OTP programming interface

Needs only 7 pins for OTP programming: VDD, VSS, VPP,

TEST, PIEP, SCK (SEG14), SDA (SEG13)

Note*: EV-board can not emulate IOB’s output function.
