Dear customer st LAPIS Semiconductor Co., Ltd. LAPIS Semiconducto), on the 1 day of October, 2020, implemented the incorporation-type company split (shinsetsu-bunkatsu) in which LAPIS established a new company, LAPIS Technology Co., Ltd. (LAPIS Technology) and LAPIS Technology succeeded LAPIS Semiconductors LSI business. Therefore, all references toLAPIS Semiconductor Co., Ltd,LAPIS Semiconducto and/orLAPI in this document shall be replaced withLAPIS Technology Co., Ltd Furthermore, there are no changes to the documents relating to our products other than the company name, the company trademark, logo, etc. Thank you for your understanding. LAPIS Technology Co., Ltd. October 1, 2020 FEDL620Q130-02 Issue Date: May 12, 2016 ML620Q131/2/3/4/5/6 16-bit micro controller GENERAL DESCRIPTION This LSI is a high performance CMOS 16-bit microcontroller equipped with an 16-bit CPU nX-U16/100 and integrated with rich peripheral functions such as the timer, PWM, comparator, voltage level supervisor, UART, I2C, and successive approximation type A/D converter. The CPU nX-U16/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipeline architecture parallel processing. It has the data flash memory area which can be written by software. In addition, the on-chip debug function that is installed enables software debugging and programming. FEATURES CPU - 16-bit RISC CPU (CPU name: nX-U16/100) - Instruction system: 16-bit length instruction Instruction set: Transfer, arithmetic operations, comparison, logic operations, multiplication/division, bit manipulations, bit logic operations, jump, conditional jump, call return stack manipulations, arithmetic shift, and so on On-chip debug function built in Minimum instruction execution time 30.5 s (at 32.768 KHz system clock) 0.063 s (at 16 MHz system clock) Internal memory Flash memory (program area) Rewrite count 100 cycles ML620Q131: 8 Kbyte (4K x 16 bits) ML620Q132: 16 Kbyte (8K x 16 bits) ML620Q133: 24 Kbyte (12K x 16 bits) ML620Q134: 8 Kbyte (4K x 16 bits) ML620Q135: 16 Kbyte (8K x 16 bits) ML620Q136: 24 Kbyte (12K x 16 bits) Flash memory (data area) Rewrite count 10,000 cycles 2 Kbyte (1K x 16 bits) SRAM 2 Kbyte (2K x 8 bits) Interrupt controller - Non-maskable interrupt source: 2 (Internal sources: BACK-UP CLOCK, WDT) - Maskable interrupt sources: 30 (Internal sources: 25, External sources: 5) - Four interrupt levels and masking function Time base counter - Low-speed time base counter 1 channel Watchdog timer Non-maskable interrupt and reset (The first overflow generates an interrupt, and the second overflow generates a reset) Free running Overflow period: 4 types selectable (125 ms, 500 ms, 2 s, and 8 s at 32.768 kHz) 1/33
