reg eaddr s:1 Table 1.2: XE8000 Instruction Set Memory organisation Program memory 8k instructions Data address bus Program address bus The CPU uses a Harvard architecture, so that memory is organised in two separated fields: program memory and data memory. As both memory are separated, the central processing unit can read/write data at the same time it loads an instruction. Peripherals and system control registers are mapped on data memory space. Program memory is made in one page. Data is made of several 256 bytes pages. RAM 512 Bytes CPU Peripherals CPU Instruction pipeline registers 22 bits wide Registers 8 bits wide Memory organization Program memory The program memory is implemented as Multiple Time Programmable (MTP) Flash memory. The power consumption of MTP is linear with the access frequency (no static current). Memory sizes: * Flash MTP: 8192 x 22 bits (= 22 kBytes) block size address MTP 8192 x 22 H0000 - H1FFF Program addresses XX/D010-060 Product Preliminary Specification Page 6 Low-Power Microcontroller XX-XE88LC01 Data memory The data memory is implemented as static Random-Access Memory (RAM). The size is 512 x 8 bits plus 8 low power RAM bytes that require very low current when addressed, programs using this low power RAM instead of regular RAM will spare even more current.

They are 3 parallel ports, one input port (A), one IO and analog port (B) with analog switching capabilities and one general purpose IO port (C). A watchdog is available, connected to a prescaler. Four 8-bit counters, with capture, PWM and chaining capabilities are available. The UART can handle transmission speeds as high as 38kbaud. Low-power low-voltage blocks include a voltage level detector, two oscillators (one internal 0.1-4 MHz RC oscillator and a 32 kHz crystal oscillator) and a specific regulation scheme that largely uncouples current requirement from external power supply (usual CMOS ASICs require much more current at 5.5 V than they need at 2.4 V. This is not the case for the XE88LC03).
