Each bidirectional port consists general purpose lines data strobe line. ports also feature configurable interrupt request output. Access X88C75 accomplished through multiplexed address/data 80C51 type controllers. internal programmable address decoder maps internal memory register locations into desired address space. ARCHITECTURAL OVERVIEW X88C75 incorporates interface circuitry normally needed decode control signals demultiplex address/data provide "seamless" interface. control inputs X88C75 configured such that possible directly connect them proper interface signals 80C51 microcontroller. reading data from chip controlled either PSEN signal, which essentially maps X88C75 into both Program Data Memory address map. Reading writing nonvolatile memory array analogous operation. During write operation either nonvolatile memory control registers, latches address written into X88C75. FUNCTIONAL DIAGRAM

rising edge latches data written. nonvolatile memory X88C75 internally organized independent arrays 4K-bytes with input selecting which planes memory accessed. While processor executing code plane, write operations take place other plane; allowing processor continue execution code X88C75 during byte page write device. This feature called Concurrent Read During Write. X88C75 also features advanced implementation Software Data Protection scheme, called Block Lock Protect, which allows nonvolatile memory array treated independent sections 1K-bytes. Each these sections independently enabled write operations. This allows segmentation memory contents into writable non-writable sections, thereby, allowing certain sections device secured that updates only occur controlled environment. (e.g. automotive application, only authorized service center). Block Protect configuration stored nonvolatile register, ensuring that configuration data will maintained after device powered-down.

This allows microcontroller write from thirty-two bytes data X88C75. Each individual write within page write operation must conform byte write timing requirements. falling edge starts timer delaying internal programming cycle 100µs: therefore, each successive write operation must begin within 100µs last byte written. waveform page illustrates sequence timing requirements.

PORTS INTERRUPTS X88C75 features 8-bit ports which equipped with configurable interrupt module. interrupts used signal reception data input port data latch. When port configured output, longer generate interrupts. input port interrupt mechanism controlled external strobe pins (STRA, STRB). Detecting valid transition will interrupt flags latch input data. external interrupts from ports masked using interrupt enable bits (ENA, ENB) ISR. Once external interrupt asserted, clearing interrupt flags will cause signal return idle state. There ways resetting interrupt flags. selection made using IRST configuration register. IRST set, then interrupt flags cleared writing positions corresponding interrupt flags (INTA, INTB) ISR. When IRST cleared, reading automatically clears interrupt flags. SOFTWARE CONTROLLED PORT OPERATIONS individual clock signals, that control input latches load external data present port pins, generated XORing strobe polarity strobe input port. strobe polarity bits (STPA, STPB) used program active edge strobe inputs. However, external strobe input permanently tied VCC, then strobe polarity controls input latch clock signal. When port strobe polarity have identical logic levels, corresponding latch active change port inputs will show latch outputs. Holding strobe input current levels changing strobe polarity value will generate positive transition clock signal, causing latch outputs reflect previous logic state port pins. clock transition sets interrupt flags, interrupts have been enabled, then external interrupt signal will asserted.

This feature allows port input operation permanently tying STRx inputs VSS, using STPx bits control latches. Another advantage this feature software generated interrupts. Since clocking latch causes corresponding port INTx flags set, enabling interrupts microcontroller forced execute responsible service newly latched data. WRITE (EOW) INTERRUPT internal programming cycle requires several milliseconds either single byte write page write. updated memory plane inaccessible while programming progress. However, opposite plane still available program fetch data read operations. X88C75 means signaling internal programming cycle. Toggle Polling technique, last written byte successively read. read data toggles while programming cycle still progress. software continually monitor device responses determine again access plane. other method, internal programming cycle, hardware sets flag. software either poll this flag enable interrupts setting ENEE ISR. Effective made clearing prior initiating write operation. interrupt enabled, external interrupt will asserted completion internal write cycle. interrupt cleared setting "0". USING PORT BIDIRECTIONAL MODE order port bidirectional mode, configured open drain output port. Small pull-up resistors required port output pins. positions Port Data Register corresponding port inputs should contain "1". inputs then read accessing PPR.
