描述 Description

The GPLB301A, an 8-bit CMOS microprocessor, contains 4288 bytes working RAM, 512K bytes OTP memory, 30 I/Os, interrupt/wakeup controller, UART for serial communication, Serial SRAM interface and Bus memory interface for memory expansion, and automatic display controller/driver for LCD. It is an OTP (one-time-programming) version for GPLB30/ GPLB32 /GPLB33 /GPLB37 /GPLB38B. The embedded OTP memory enables users to customize application programs fast and conveniently. Users may use GPLB301A for prototyping and then use GPLB30/ GPLB32/ GPLB33/ GPLB37/ GPLB38B for mass production. The pin sequence of GPLB301A is compatible with GPLB32 and GPLB37. It also features one PWM driver with two audio channels to produce attractive sound effects easily. Its large OTP area can be used to store both program and audio data (speech duration approx. 138 seconds at 7KHz sampling rate using a 4-bit ADPCM). The built-in UART speeds up data transmission between two devices. Furthermore, a SLEEP (power-down) function is also built in to extend power life. The GPLB301A is designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
