MN102L490A

The MN102L490A is a very good product.

There is some information about the specifications: (1)ROM (*8 bit/*16 bit): external; (2)RAM (*8 bit/*16 bit): 3K; (3)minimum instruction execution time: with main clock operated: 100 ns (at 4.5 V to 5.5 V, 20 MHz); (4)interrupts: RESET, watchdog, timer counter 0 to 5, time counter 6 to 7, time counter 6 to 7 compare capture A, timer counter 6 to 7 compare capture 8, ATC transfer finish, external 0 to 4, serial ch 0, 1 transmission, serial inch 0, 1 reception, NMI pin and ADI conversion finish; (5)serial interface: serial 0: 7, 8 bit*1 (common use with UART, transfer direction of MSB/LSB selectable): clock source: 1/16 timer counter 2, 1/16 of time counter 3, external clock, 1/2 of timer counter 2; serial 1: 7, 8 bit*1 (common use with UART, transfer direction of MSB/LSB selectable): clock source: 1/16 timer counter 2, 1/16 of time counter 3, external clock, 1/2 of timer counter 2; UART*2 (common use with serial 0, 1); I2C*2 (single master); (6)A/D inputs: 8 bit*8 ch (with S/H); (7)PWM: 16 bit*2 ch; (8)package: LQFP100-P-1414.

The following is about the electrical characteristics (at VDD=5 V): (1)A/D conversion relative error: ±3 LSB max at VDD=5 V, VSS=0 V, ch0 to 3 and ±4 LSB max at VDD=5 V, VSS=0 V, ch4 to 7; (2)A/D conversion time: 48s min; (3)analog input voltage, VIA: VSS V min and VDD V max.
