IS31SE5114 is a general-purpose micro-controller with 64K embedded flash memory and 2K SRAM. Extensive peripherals are included targeted for embedded system with LCD/LED displays. The CPU is based on 1-T 8051 with T0/T1/T2 and additional 16-bit T3/T4, 24-bit T5 and a 30-bit WDT. Embedded in the CPU core are also a full-duplex UART port, an enhanced EUART port with LIN capability, one I2C master/slave and two I2C pure slave controllers, one SPI mater/slave controller, up to 55 GPIO pins with each GPIO pin configurable as external interrupt and wake up. The flexibility in clock setting includes an on-chip precision oscillator with the accuracy deviation of +/- 2%, or a low power internal 32kHz oscillator, or an ultra low power precision real time clock (RTC) and a programmable PLL up to 10MHz. The clock selections are combined with flexible power management schemes, including NORMAL, PMM, IDLE, and STOP, and SLEEP modes to balance CPU speed and power consumption. The built-in LCD controller can support up to 8 common and 28 segment output with ½ , ⅓ or ¼bias. When configured as LED controller, it supports a direct-drive mode that can drive up to 8 SEG by 15 digits with 64-level brightness control. A Programmable Counter Array (PCA) with 6 channels of Capture/Compare/PWM modules can be used for various purposes controlling external devices. There are additional 2 independent 8-bit PWM and a buzzer waveform generator with frequency range of 128Hz to 2048Hz and programmable duty cycle. Analog peripherals include a high performance 12- bit Analog to Digital Converter (ADC) with 30usec conversion time. There is an on-chip temperature sensor within the ADC block. IS31SE5114 also provides a flexible means of flash programming that supports ISP and IAP. The protection of data loss is implemented in hardware by access restriction of critical storage segments. The code security is reinforced with sophisticated writer commands and ISP commands. The on-chip break point processor also allows easy debugging which can be integrated with ISP. Reliable power- on-reset circuit and low supply voltage detection allows reliable operations under harsh environments.
