JTMP04020-XXXS

The JTMP04020-XXXS is a kind of high-performance LL microcontroller developed for use in contact-type personal reader/writers. The JTMP04020-XXXS combines a 4-bit high performance CPU, memory (work RAM, data RAM, and program ROM), LCD LL controller driver, multi-function timers, IC card power supply (3 V/5 V switchable), IC card interface, external memory interface, and battery detector circuit on a single chip.

There are some basic features of JTMP04020-XXXS as follows: (1)number of instructions: 56; (2)minimum instruction execution time: 61s (at 32.768 kHz); 57s (at 35 kHz); 1s (at 2 MHz/3.0 V); 560 ns (at 3.58 MHz/4.7 V) ; (3)built-in ROM size: 16K words 1 word=16 bit); (4)built-in RAM size: work RAM: 512*4 bit; data RAM: 6 Kbit; display RAM: 544 bit (16 com*34 seg) and 336 bit (8 com*42 seg); (5)input pin: 8 pins (with interrupts); (6)input/output pin: 12 pins (output pins for key strobe); (7)output pin: a pin for buzzer output; (8)interrupts: 4 external interrupts (input pin, IC card I/F, external memory I/F) and 3 internal interrupts (timer/counter, timing); (9)timer: 8 bit*2 ch or 16 bit*1 ch (switchable by software); (10)LCD display driver controller: 34 seg*16 com or 42 seg*8 com; (11)watchdog timer: timer/counter can be used as watchdog timer; (12)operating power supply voltage: 3.0 V @ f=2 MHz/4.7 V @ f=3.58 MHz.

The following is about the maximum ratings of JTMP04020-XXXS (Ta=25): (1)supply voltage, VDD: -0.3 to 6.0 V; (2)input voltage, VIN: VDD+0.3 to GND-0.3 V; (3)operating temperature, Topr: 0 to 40; (4)storage temperature, Tstg: -55 to 125.
